Thanks Robert. I did some research on IGD message as hinted by you and got this link https://www-01.ibm.com/support/knowledgecenter/SSLTBW_2.1.0/com.ibm.zos.v2r1.ieam800/iea3m8_IGD_messages.htm From there I find these related to SPACE: IGD17004I NOT ENOUGH SPACE FOR PDS DIRECTORY ON VOLUME vol FOR D...

Based on the input files' first two characters and then the characters at position 12-13. We are aiming to use COBOL. These two are from the interview. Other questions I made up, not because I wanted to cheat but I wanted to learn more. I saw your replies on other posts and was sure that you can gi...

If the allocation is done on a volume that does not have 40 free cylinders available in 5 extents, you'd get a space ABEND. The number of records is irrelevant to this issue. If the data set is under SMS control, you won't get a space ABEND at all. SMS will give you messages about how many volumes ...

- How do you know how long each output record should be? Based on the input files' first two characters and then the characters at position 12-13. - Where do the extra bytes come from for records that are longer than the 80 byte input length? That is we are not sure at this moment. But for now we c...

Hi, This question is related to SB37 I am sure but as it was asked I could not answer it. Can someone help me. The question is, if a file, file-1, has just 10 records while the DD statement for it has the space allocation as SPACE=(CYL,(40,10)). But we still get a space abend. Tell us why would this...

Hi,

I need help in this interview question:

If the input file have a fixed record length as 80. But output file should have records with different lengths. Output file should have first record of say length 100, second record of 75, third is of 80. How can we do it, write a pseudo code.
