Marianne,
See www.asciitable.com for the ASCII characters table.
Control characters, as you can see from the ASCII table, are defined at the front (values 0-31). Printable characters are basically defined between 32 and 126. Values 127 to 255 are other special characters and accented characters.
Assuming the character is a lowercase letter, I believe this is intended to upshift it. It's hard to tell without the context where the Compute is used (variable definitions, Cobol statements before/after).

Subject: [HP3000-L] Cobol - Ordinal Position/Control Character
Hi everyone,
In a COBOL program, if I have this line:
compute var = function ord(<certain char>) - 161
what does it actually compute?
Also, if you happen to know too. Given that's how to compute a certain
character (above equation), would you know the range of integer of control
characters? Or even just the ordinal position of all control characters [function
ord()]?
Thanks a lot! =)
