( #3333=superdoc: print w/replies, xml ) Need Help??

My EBCDIC and COBOL skills are very low, I'm new to this old technology.

I have some COBOL records EBCDIC encoded files. Each file is a list of records. I want to convert it into a Perl data structure, perform some transformations on fields, convert back to COBOL data structure and EBCDIC encoding.

I've found the Convert::EBCDIC CPAN module of course, but the COBOL record definition is not obvious for me : I don't understand how to jump from the COBOL definition to the unpackeb pattern :-/ Prior to this field extraction, I don't understand how to extract lines from the file !

My COBOL definition is:

01 BCOM. 05 FILLER-ASCII PIC X(292). 05 FILLER-EBCDIC1 PIC 9(8) COMP. 05 FILLER-EBCDIC2 PIC 9(8) COMP.

what should the pattern be to unpack fields?

Convert::EBCDIC module on CPAN

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
