Consider getting one of the mainframe coders to write a small bit of ANSI COBOL. Use that to transform the packed data.

Here is a discussion of the COBOL needed.
Packed Decimal
IF you have Microfocus COBOL on UNIX you can compile and run it there on the UNIX box. If you really want to spend some time consider C. There is not much I can see out there in the way of C code to convert packed decimal data.

We had a similar requirement to transfer vast amounts of data across a small network link from one site to another. We used PKZip from PKWare to achieve it. There is a cost to the software I think, but it did the job beautifully. We closed our window for data transfer from 38 hours to about 6 - obviously we had plenty of CPU available to do the compression part.

Results will vary depending on the data volume, data structure, the CPU available and the network speed, but it was pretty impressive. The EBCIDIC to ASCII conversion was handled, but we could not send packed data and we had to be careful with unusual characters, e.g. those with accents etc.

I'm sure other vendors may also be able to help you too.

If you wish to do more work yourself, see perl code at https://metacpan.org/pod/distributio...ert/IBM390.pod :
Quote:
Convert::IBM390 supplies various functions that you may find useful when working with IBM System/3[679]0 data. No functions are exported automatically; you must ask for the ones you want. "use ... qw(:all)" exports all functions.

By the way, this module is called "IBM390" because it will deal with data from any mainframe operating system. Nothing about it is specific to z/OS, or z/VM, z/VSE, i5/OS, z/TPF....

When transmitting EBCDIC data to your Perl environment via FTP, be sure to use the "binary" option. This will leave the data unconverted so that the module recognizes it. By default, FTP will translate the data to ASCII; this will convert the character fields correctly but garble other formats, such as packed-decimal and binary.
which then allows:
Quote:
unpackeb TEMPLATE RECORD
This function is much like Perl's built-in "unpack". It takes an EBCDIC record (structure) and unpacks it into a list of values. If called in scalar context, it will return only the first unpacked value. The TEMPLATE is patterned after Perl's unpack template but allows fewer options. The following characters are allowed in the template:

c or C (1) Character string without translation
e (1) EBCDIC string to be translated into ASCII; preserve
trailing nulls and spaces
E (1) EBCDIC string to be translated into ASCII; strip
trailing nulls and spaces
i (2) Signed integer (S/390 fullword)
I (2) Unsigned integer (4 bytes)
p (1) Packed-decimal field
...
Best wishes ... cheers, drl
