I want to check number of lines in the source code of cobol on mainframe. cobol source code resides in one of the PDS on mainframes.
Note: I am new to Mainframe OS. Previously I was working on AS/400 OS. Trying to see Mainframe OS through IBMi lens.
If all the source code is in one dataset or PDS member, simply Edit or View the dataset and issue the primary command 'X all' to exclude all lines. There will be an information line showing how many lines are excluded which - because you excluded ALL lines - will be the number of lines in the dataset.

I want to test an application with a file containing 10000 lines of records (plus header and footer lines). I have a test file with 10 lines now, so I want to duplicate these line 1000 times. I don't want to create a C# code in my app to generate that file (is only for test), so I am looking for a different and simple way to do that.
What kind of tool can I use to do that? CMD? Visual Studio/VS Code extension? Any thought?
If your data is textual, load the 10 records from your test file into an editor. Select all, copy, insert at the end of file. Repeat until the file is of length 10000+
This procedure requires ceil(log_2(1000)) cycles, 10 in your case, in general ceil(log_2(<target_number_of_lines>/<base_number_of_lines>)).
Alternative (large files)
Modern editors should not have performance problems here. However, the principle can be applied using a cat cli command. Assuming that you copy the original file into a file named dup0.txt proceed as follows:
cat dup0.txt dup0.txt >dup1.txt
cat dup1.txt dup1.txt >dup0.txt
leaving you with the quadrupled number of lines in dup0.txt.
I have an STM32 application which uses two blocks of memory. In 0th block, I have a boot code (which runs just after power-on) and in 7th block, I have an application code (which may or may not run depending on the authorization decision given by the boot code).
Those two codes are developed hence generated by two separate projects. They are flashed on the specific blocks (boot code to 0th block and application code to 7th block) of STM32 NOR memory using openocd tool by giving an offset value to the openocd's write_image command.
What I would like to do basically in the boot code is that I want to calculate the hash of the application code and compare it with the reference digest. If they are equal, I will give the hand to the application code. For that, after I generate the executable (can be in elf, hex or bin format) of the application code, I want to:
Create another file (in any format listed above) which has 128K byte size
Copy the content of the executable file to the recently created file from its beginning (0 offset)
Write the hash of the executable to the last 32 bytes of the recently created file
Fill the gap with 0xFF
Finally flash this executable file (if it is still) to the 7th block of the memory
Do you think that it is doable and feasible? If so:
Which format should I use to generate the executable?
Do I have something that I need to give specific attention to achieve this?
Lastly, do you think that it makes sense to do that or is there any other more standard way for this purpose?
Thanks a lot in advance.
You just need to add an additional step to your building sequence. After the linking extract the binary file from elf
Then write a program in your favourite programming language which will calculate something and append the result to that bin file
UPDATE: in the workbench/J log file I am seeing this error:
ERROR Variable names may only contain characters (a-z, A-Z), numbers and underscores
I'm sure this is what is causing my process to fail, but I have no idea why because my variables are named appropriately. I've tried renaming them a few times just in case and the same thing happens.
ORIGINAL POST:
I am working on an automated process to dump the contents of a Postgres query to a text file and FTP it to someone. The process I have been using successfully is a windows batch script that runs SQL Workbench to run the query and write the entire contents of the table to a text file and FTP it.
Now I want to be able to use WBVarDef to load a variable from a text file and use it in my query. For reference, the variable is the unique id of the last record that was FTPed. This is the code i have:
WBVarDef -variable=id -contentFile=id.txt;
WBVardef today=#"select to_char(current_date,'mmddyyyy')";
WBExport -type=text
-file='c:/CLP/FTP/$[today]circ_trans.txt'
-delimiter='|'
-quoteAlways=true
-lineEnding=crlf
-encoding=utf8;
SELECT
*
FROM
transactions
WHERE
transactions.id > $[id]
ORDER BY
transactions.id;
The only thing new here is the reference to the text file that contains the id on the first line. This completely breaks the process but as far as I can tell, I am using this according to the SQL Workbench documentation.
Any help would be greatly appreciated.
I have figured this one out. I was running an older version of workbench that did not support this functionality. Now that I upgraded to build 119 this is working. I'm having other issues but that's a different story....
My team has been using Notepad for translation purposes so far. Recently, we decided to use one of the CAT tools available on the Internet - OmegaT.
We've got source and manually translated files, and only values were ever touched.
Is it possible to import both to the same project, so that source phrases stay source, and our phrases become their translated counterparts?
Note: I don't know if it matters, but files are formatted as INI (key=value).
What you need is an alignment. It takes source and target files and creates a translation memory.
In your specific case (INI files), you can use OmegaT to do an automatic alignment with a command line:
http://omegat.sourceforge.net/manual-standard/en/chapter.installing.and.running.html#omegat.command.arguments
Sample command line:
java -jar OmegaT.jar "C:\OmegaTProject" --mode=console-align --alignDir="C:\OmegaTProject\align"
For more general purposes, and with a GUI, there's a prototype version of OmegaT with an aligner:
https://omegat.ci.cloudbees.com/job/omegat-prototype/26/
See the OmegaT development mailing list for information about this.
Didier
With currently Beta version of 4.* releases (currently 4.1.5), you can use nice visual aligner - https://www.proz.com/forum/omegat_support/306343-new_interactive_aligner_in_omegat.html
I have a crystal report which contains a list of absolutely referenced text files. There is one text file referenced in each body line.
e.g.
line1 c:\file1.txt
line2 c:\file2.txt
Is there any way to display the contents of these files in Crystal?
i.e. I would like each crystal body line to show the text from the referenced text file.
I'm using Crystal reports 11 with a non-standard database connector (dataflex).
You would need to set up a file dsn (in XP it's under Control Panel/Administrative Tools/Datasources (ODBC)) and then use the file dsn (Microsoft Text Driver) for the datasource as an ODBC(RDO) connection.
I set this test scenario up on mine like the following:
**File 1**
column1
1row1
1row2
1row3
**File 2**
column1
2row1
2row2
2row3
I set up the file dsn to point to the c drive and in the datasource screen I added file1.txt and file2.txt to the selected tables. Then the easiest thing to do is clear the links of the tables so that it pulls every row. It will warn you that there are multiple starting points. I don't generally recomend this, but it will work in this case and since it's not reporting off a database it probably isn't the end of the world. If you disregard the starting point message then add the fields to the report, when you run it you should get the following output:
1row1 2row1
1row1 2row2
1row1 2row3
1row2 2row1
1row2 2row2
1row2 2row3
1row3 2row1
1row3 2row2
1row3 2row3
From this you can change your grouping to get the output that you need.
You can also use this same connect against subreports instead of doing this linking where you have the main report pull the info from file1.txt and then put a subreport in the report footer that pulls from file2.txt. This option won't have the text collated, but you'd still have it in the same report.
Hope this helps some.
It's easier than you think. I just set up one myself before I wrote this to make sure I was giving you the right steps. Using CR version XI and a .txt file, I followed these steps:
For each text file you want to import, make a subsection in your report (i.e. DetailsA, DetailsB, etc.). If your list of text files is constantly changing (and I don't think it is, based on your description), you'll need another method.
Make sure your text file is comma delimited and the first row contains field names. If these text files are actually text (i.e. not tables), then just put a dummy variable name in the first row so Crystal will see the text as a table of data with just 1 row.
For each text file you want to display, create a new Subreport (Insert->Subreport)
In the database selection menu, go to "Create New Connection"->"Access/Excel (DAO)"
Under 'database type', you'll see a 'text' option at the bottom of the screen.
Choose your file.
Relax! (I'm in a good mood this morning, don't know why)
I guess if you have a function that takes a file name as an argument and returns the contents of that file - you could use that function in a Crystal Report formula.
I am not familiar with the current CR, it has been years since I last used it (I last used version 8). In the versions I did use, such a function was not built in. What you would have to do back then, was to create a UFL (user function library) containing the functions you needed. If I remember correctly, you had to do this using COM.
In this day and age, I guess you can extend CR using some other mechanism, perhaps writing .NET code?
I suggest you search the CR documentation for the term UFL.
Another suggestion, then:
Create a new table FILECONTENTS (filename varchar primary key, contents blob)
Create a script that on a schedule populates this table with the filenames and contents of all the files (assuming that there is a finite number of files, and that you have a way of knowing about them)
Modify the report datasource query to join it with the FILECONTENTS table, and add the contents field to the report.
You could setup a file dsn. But this is geared toward tabular file data, not text.
How big are these text files? You want to display the entire contents of each file?
There is probably no easy way to dynamically read in a file from within crystal. You will most likely have to push a dataset to the report which contains the file contents.
