convert Regular decimals to Packed decimals

mgirinath · #1 (**permalink**) 09-19-2008

Hi,

I am trying to find if there is a way to convert regular decimal values to Paced decimal values. I tried to find a c program but I could get a Packed converted to regular decimal not the other way round.

If not unix please let me know if any other progrimming language I can use to do this.

Thanks.

Hi.

If you are comfortable in perl, there is this module at http://cpan.org/:

Code:

Convert::IBM390 -- functions for manipulating mainframe data

providing, for example:

Quote:

packeb TEMPLATE LIST

This function is much like Perl's built-in "pack". It takes a list of values and packs it into an EBCDIC record (structure). If called in list context, it will return a list of one element. The TEMPLATE is patterned after Perl's pack template but allows fewer options. The following characters are allowed in the template:
...
P (1) Packed-decimal field with F signs for positive numbers
(sometimes called "unsigned") (default length = 8)

You might also Google for packed decimal unix

I have used a COBOL compiler on Linux: OpenCOBOL - an open-source COBOL compiler ... cheers, drl

There are a number of different types of packed decimals. If you want IEEE 754r:2008 types have a look at the decPacked module in the IBM decNumber library alphaWorks : decNumber : Overview. It is witten in ANSI C.
