RE: ASCII support in z/OS
Message ID:
I hope I'm understanding you on this.

Users of perl on z/OS, work almost exclusively in EBCDIC.
I understand from a porting Point of view.  However if fixing a porting issue introduces to USS (OMVS) that our files are ASCII encoded.
I do not believe you'll find many users who will find that acceptable.   I do not find it acceptable myself.

I am talking purely from the end user POV,   ascii encoding is useless to many if not all of us.  If it introduces the need for us to chtag files so we can encode them basic to EBCDIC the way they should have been encoded by default. The overhead of doing work on zOS jumps and the value of perl goes down.

Remember,  we don't exclusively work in OMVS.   Most of what we'll do is z/OS datasets   those have no CHTAG option.  
Coping to USS is often not an option either due to size or confidentiality/integrity of data especially in the financial industry.

That said, what perl does internally, I don’t' care,   what perl does to files and datasets I do care very much.
A file with no chtag should be read as EBCDIC
A file with a chtag of ISO-885901 should be read as ASCII.

The main problem, obtain new tools to z/OS. tools is  very outdated on USS z/OS.

This will leave the encoding EBCDIC and go to the encoding ISO-8859-1 on USS.
and is able to build newer versions of the tools with minimum work on porting.

If the community perl knows about encoding EBCDIC , the community git does not know about it.

turn on the system ASCII support is much easier than working with the encoding EBCDIC .
