Re: scanning for a hex value in RPGIV

["Mike Naughton" <mnaughton@xxxxxxxxxxxx>]

Hi Shannon,

I can't tell you why your scan is failing, but I can tell you that
scanning for hex values works fine (I have used it to to search for null
values in data passed from other systems, and it's very handy). I just ran
a little test:

1. I set up a test file with the following DDS:
A          R TEST
A            TESTFLD       24

2. Then used DBU to edit the file and add a record with "TEST VALUE"

3. Then used the hex editor to change the space between TEST and VALUE to
x'B6'
TESTFLD  TEST¶VALUE
         ECEEBECDEC44444444444444
         352365134500000000000000


4. Then wrote a simple program:
FTEST001PF IF   E             DISK
D                 DS
D  POS                           2  0
D  PARA           S              1    INZ(x'B6')
C                   READ      TEST
C     TESTFLD       DSPLY
C                   Eval      POS = %SCAN(PARA:TESTFLD)
C     POS           DSPLY
C                   EVAL      *INLR=*ON
C                   RETURN

5. Here are the results of the program:
DSPLY  TEST¶VALUE
DSPLY  05

So what you're trying to do should work fine.  (Usually when that happens
to me, I find it's something really simple. . . .  :-)
