This can’t be done with JCL or VSAM. Show us Input, desired Output, and what you have tried so far.

In this terminology, it cannot be done, physically.

It is like this

The "ASCII data" is actually a free-format text string in specific encoding (not really used on mainframe, in normal circumstances!!!)

The "COMP-3 data" is a COBOL-specific term referring to a much more general one of IBM mainframe internal numeric formats known as packed decimal format

Unless you understand the meaning of all those terms, the only thing you can do: ask somebody to do your job in full for you to copy-and-paste the result of their work as if it was done by yourself.

Some people might be so kind to do your full job, from top to bottom, and to give you their results. I will not start classes for lazy schoolboys on this forum.

Additional stop mark for myself: you have even no idea what is JCL (to say nothing of VSAM). No starting point to begin any discussion.
