RE: Reading source files in RPGLE



fixed

Rob,
We have a local program I use to replace "color attribute bytes" with blank characters.
This is to "fix" older source maintained by SEU so it can be maintained with RDi.
I can post the source to midrange, but have forgotten how so someone will need
to out-line that process for me, or I can put in a save file and e-mail directly to you.
The RPGLE code defines the update file as program-defined with 1000 bytes per
record so it's picky about the file being source pf or not.

Subject: Reading source files in RPGLE

I haven't needed to read a source file for about 24 years and didn't have any problems reading them with OPM RPG.

Now I need to do it again and am using RPGLE. I can open the file and read records but the fields are all empty. I must be doing something pretty dumb. I am on V5R1. Can anyone help please? I have tried with both externally described and program described files.

The code below is for the program described version

The file is defined in the program with

0001.10 FERPGLESRC IF F 112 DISK
0001.11 F USROPN

It is a full procedural file

The Input fields are

0248.39 IERPGLESRC DS
0248.40 I 1 6 2SRCSEQ
0248.41 I 7 12 SRCDAT
0248.42 I 13 112 SRCDTA

and the file statements are

0496.32 * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
* * *
0496.33 C/SPACE
1
0496.34 C FNPEXT
BEGSR
0496.35 C/SPACE
1
0496.36 C Read ERPGLESRC
5152
0496.37 C/SPACE
1
0496.38 C
ENDSR
0496.39 * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
*
0496.40 C/SPACE
1
0496.41 C FNP#1O
BEGSR
0496.42 C/SPACE
1
0496.43 * This subroutine opens the source file
0496.44 C OPEN ERPGLESRC
51
0496.45 C MOVE 'Y'
OPNSRC
0497.08 C/SPACE
1
0497.09 C
ENDSR
0497.10 C/SPACE
1
0497.65 * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
*


I then do an override before calling the program

OVRDBF FILE(ERPGLESRC) TOFILE(E290PRDSRC/QRPGLESRC) MBR(E29RPP)
POSITION(*START)


I do a debug after the read statement and all the fields are empty but the correct file member is open - I have checked the job using WRKACTJOB

I shall probably be embarrassed by the simplicity of the answer

Many thanks.
