Porting to USS has (at least) two significant hurdles: EBCDIC
How much is that mitigated by Enhanced ASCII? What residual
problems remain? Unsupported library functions?
A couple of additional problems you can encounter:
- code that ASSumes that lower case alphabetic characters collate
higher than upper case alphabetic characters;
- code that ASSumes that all lower case alphabetic characters
are in a contiguous range of hex values (similar for upper case);
- code that ASSumes that digits collate lower than alphabetic
characters.
Some years ago, I was investigating porting a well-known database
package that shall remain nameless to z/OS USS, and found that the code
had a lot of the above.
