ROTF,LMAO

The issue is not what the code does, the issue is what the syntax diagrams say.

Again, comments without any supporting facts. It's only been a couple weeks 
since your last non-sense wasted my time.

Mutually exclusive would issue an error message. I asked Gemini AI "what 
happens to conflicting parms in tso commands?" which came back with the correct 
answer.

In TSO (Time Sharing Option) commands on IBM mainframes, when you specify 
conflicting parameters, the general rule is that the last specified parameter 
for a given attribute takes precedence. This means the system will use the 
value provided by the parameter that appears latest in the command string, 
overriding any earlier, contradictory specifications for the same attribute.

For example, if a command allows you to specify a file's disposition as either 
NEW or OLD, and you type:

ALLOCATE DSN('MY.FILE') NEW OLD

The OLD parameter would typically override NEW because it's the last one 
encountered.

Gemini also responded with: This is a common design pattern in command-line 
interfaces.

Those arrows indicate conflicting parms but nothing about how conflicting parms 
are handled.

Unix is relevant because it too has commands but is inconsistent on how 
conflicting parms are handled. TSO command parser consistently handles parms.
