Apologies in case some thread already present on this.
I need to remove some punctuation marks/invalid data from a PS file read by REXX. How this can be achieved via REXX? Any pointers would be useful.
Thanks - Nilesh |

1) What is your level of knowledge about REXX?
2) Why REXX, not any of 100500 other tools?
3) Your goal can be achieved via REXX by means of using various REXX statements, and functions. Do you know what a REXX statement is? Do you know what a REXX function is?
4) A PS dataset (not file!!!) cannot be changed in-place. Another (updated) dataset needs to be created. Do you understand this? If not, you must start from learning the basics of zOS, before going to REXX. |

EXECIO DISKR to read the dataset to a stem or the stack.
Use the POS function to find data, then use the DELSTR function to remove it.
EXECIO DISKW to write the dataset from the stem or stack.
You can use EXECIO DISKRU and EXECIO DISKW to read and rewrite one record at a time, but DISKR, process the data, then DISKW is probably simpler and safer. |
