Hi All,
Can anyone explain how to update a line to the dataset.
Here in the below code I am trying to update the second line by 'XXX'. Here it is writing XXX but not updating.
| Code: |
"ALLOC FI(MYINDD) DA('INPUT.DATA.SET') OLD REUSE"
"EXECIO * DISKRU MYINDD (FINIS STEM NEWVA."
NEWVA.2='XXX'
PUSH NEWVA.2
"EXECIO * DISKW MYINDD (FINIS" |

| Keep in mind that REXX only uses QSAM for file processing. |

1. Read the whole thing into a stem using EXECIO
2. Insert your new line. Likely, you will have to copy to a different stem.
3. Use EXECIO to write the new stem and replace the old member. |

The EXECIO command is well documented in the fine manual.
