PugSA has asked for the wisdom of the Perl Monks concerning the following question:

Hi
I was recently asked to convert Ascii to ebcdic packed for a os390 mainframe, I'm using the packeb function but the client says it is not the desired output. I'm a bit clueless of the mainframe enviroment, if there is someone that can advise.
I wrote a small script just to test the output here goes:...

Difinition & Layout
These are 6 fields of a 97 field layout
--------------------------------------------------------
FLD W 80 A
FLD-1 FLD 2 P VALUE 001 Pic s9(3) Comp-3
FLD-2 FLD +02 2 P VALUE 001 Pic s9(3) Comp-3
FLD-3 FLD +04 3 P VALUE 00000 Pic s9(5) Comp-3
FLD-4 FLD +07 2 P VALUE 000 Pic s9(3) Comp-3
FLD-5 FLD +09 3 P VALUE 00000 Pic s9(5) Comp-3
FLD-6 FLD +11 5 A VALUE 'FNUT ' Pic x(5)
---------------------------------------------------------

Code
Here is the code I tried. I don't know how to test the output I currently send it to the client,to test it on the mainframe, but if you know of a win32 viewer that I can use to test the output for OS390, will be awsome.
-----------------------------------------------------------
#!c:\perl\bin\perl -w use Convert::IBM390 qw(:all); unless (open(OUTPUT, ">a2e.txt")) { die ("cannot open configuration file \n"); } @var=("001","001","00000","000","00000","FNUT"); foreach(@var) { print $_; } #$template='p1.0 p1.0 p3.0 p1.0 p3.0 E5'; $template='p3 p3 p5 p3 p5 E5'; $ebout = packeb($template, @var); print OUTPUT ($ebout);
-----------------------------------------------------------

Thank You

    perldoc -f binmode
      As warned by an anonymous monk the IBM390 module removes leading zeros when converting it to ebcdic packed. Does anyone have a sollution for this I've been stuck for over a week now and I'm not to sure how the binmode will help me (still need allot to learn) Thank You
      I've been wandering through the monastery, and found discussions on ascii to ebcdic conversions.Someone refered to dd please what is it.
        I'm unfortunately still on windows thats why I didn't know
