Re: changing two fields in a file

["James W. Kilgore" <qappdsn@xxxxxxx>]

The numeric length change isn't a problem with CPYF *MAP, it's the alpha to
numeric that has the potential to give you some problems.  It also means you
can't use CHGPF or CPYF.  And you're close, a 16 line program just might do it.

IMO, you would have to check the integrity of the alpha field first.  A simple
program where the file is program defined and you test the contents of the alpha
field to be 0->9 and maybe update blank to zero or whatever default you want 
(are
negatives allowed? N=neg 5).

If you compile the conversion program in RPGII and define the alpha input as
numeric, it will trust you (God like) and default to convert blanks to zeros and
you can z-add your 1 byte to 4 byte field.  The remaining 108 fields can be
lumped together,

If the test shows no -real- problems, how's this: (spacing not correct)

    Finput   IP  f        xxxx        disk
    Foutput  O   f        xxxx        disk
    Iinput    ns    01
    I                            1     xx part01
    I                            xx    xx0one24a
    I                            xx    xx part02
    I                            xx    xx0one24N
    I                            xx    xx part03
    C            Z-addone24a    out4a    40
    C            z-addone24N    out4n    40
    Ooutput    d    01
    O                part01    xx
    O                out4a     xx
    O                part02    xx
    O                out4n     xx
    O                part03    xx
