I recently ran into a question that I didn’t know the answer to. The question
was, what code page are dataset names and other z/OS artifacts coded in? Since
the special characters like #, $ and @ are different in codepages 1047, versus
037, etc does z/OS use one code page for these artifacts and translate if a
data set is created with JCL created with 1047 and is later accessed using an
037 code page for instance ?
I suspect someone out there has experience and knows the answer.
The devils is in the details.
You mentioned dataset names *and* other z/OS artifacts.
For dataset names and JCL keywords we use very basic subset of character
set: A-Z, 0-9, (), /, comma, dot, and some other punctuation characters,
and three "national" characters.
There is no problem with alphanumeric and punctuations used in JCL
and/or DSNs. As Gil wrote, there is no big pain with #,$,@.
I use both EN-US and Polish (and sometimes other) codepages - no
problems withe the above names.
Now we have "other z/OS artifacts". What artifacts???
Maybe unix file names?
Well, I can create file named *. Yes, it is misleading. And no, don't
try to delete it using rm *. :-)
However in many places one can put quite weird characters. Some of them
can be "codepage-specific".
My idea is to *avoid it* as it is very troublesome. However sometimes
possible.
And now it's the time for our old, favorite complaints on [] square
brackets popular in C code or | pipe characters in REXX and other
languages. The last one is translated to ! in Polish CP-870. Did I say
it is translated? No, it is *sometimes* translated and sometimes not.
Good trap for newcomers. That's why I prefer XMI over plain txt.
