Embarassed

I am trying to change a character string in a line of JCL.
IE.

OPEN DATASET test1(mem1)

Change '?yr?' to '2004' (regardless of location)

Write to DATASET test2(newmem)

Is there a quick and dirty war to do this without a great deal of code.
Much appreciated.

Hi POLSKICASHCOW,

You can use File Aid for this requirement.
Use F.3.6 Batch or Online
Go to Unformatted Selection Criteria for conditions you want.

I'd go with a straight PARSE command:

Code:

"EXECIO 1 DISKR jclin"
If rc = 0 Then
  Do
    Pull the_rec
    /* The variable 'rgt' will only contain data when
        the PARSE is successful */
    Parse Var the_rec lft '?yr?' rgt
    If Length(rgt) > 0 Then the_rec = lft||'2004'||rgt
    Push the_rec
    "EXECIO 1 DISKW jclout"
  End

Code:
ADDRESS ISREDIT
" C ALL '?YR?' '2004'"
"SAVE"
"END"

Run this on dataset(s) either online / batch.
