Hi,

I would like to change the below line

FROM

=COLS> ----+----1----+----2----+----3----+----4----+----5----+----6----+----7--
****** ***************************** Top of Data ******************************
000001 05 FILLER PIC X(22) VALUE 'XXXXXXXXXXXXXXX'.

TO

=COLS> ----+----1----+----2----+----3----+----4----+----5----+----6----+----7--
****** ***************************** Top of Data ******************************
000001 05 FILLER PIC X(22) VALUE
000002 'XXXXXXXXXXXXXXXXXXXXXX'.
****** **************************** Bottom of Data ****************************

Is there any possibility of changing as above using string concepts in REXX...

Thanks
Shakti

This piece of code should do.

Code:


"ISREDIT (SEGLINE) = LINE .ZF"       
SEGL1 = SUBSTR(SEGLINE,1,29)         
SEGL2 = SUBSTR(SEGLINE,29,51)       
"ISREDIT LINE .ZF = (SEGL1)"         
"ISREDIT LINE_AFTER .ZF = (SEGL2)"   



However you might need to customize it based on your requirement.

the snippet will only manipulate the line ...

here is the snippet
Code:
line0 = "05 FILLER PIC X(22) VALUE 'XXXXXXXXXXXXXXX'."
say "line0  >>" || line0 || "<<"
offst = pos("VALUE",line0)
line1 = left(line0, offst+5)
line2 = substr(line0,offst+6)
say "line1  >>" || line1 || "<<"
say "line2  >>" || line2 || "<<"


here is the result
Code:
line0  >>05 FILLER PIC X(22) VALUE 'XXXXXXXXXXXXXXX'.<<
line1  >>05 FILLER PIC X(22) VALUE <<
line2  >>'XXXXXXXXXXXXXXX'.<<
