jitu,
Follow this approach.
1) Read the template JCL in a stem variable
2) Form a loop and queue the lines one by one checking for the "PR99999999" using POS.
3) When PR99999999 is found, find the length, use LEFT/RIGHT to find the exact position of the data and overwrite the data entered by the user.
4) Queue the line till the last line.
5) Write the lines into a new/old dataset depending on your requirement.
Loop shd be like this
JCL should be read into a stem variable B
| Code: |
do j = 1 to no_of_lines
posx = pos("99999999",B.J)
if posx > 0 then
do
b.j = strip(b.j)
len = length(b.j)
lstr = left(b.j,posx-1)
rstr = right(b.j,len-posx-7)
line = lstr||userdata||rstr
queue line
end |
Use the above code as the base and develop your REXX. |

Or you could use ISPF EDIT macro
REXX code
| Code: |
"ISPEXEC EDIT DATSET('"Your dataset name"') MACRO(MACROE1)"
|
Macro code
| Code: |
/* REXX */
"ISREDIT MACRO"
"ISREDIT C 'PR99999999' 'New value' ALL"
"ISREDIT END" |
