All command options/qualifiers can be specified with a leading "-" character, a leading "/" character, or with no special leading character. (This allows UNIX or VMS compliant command line invocation).
Those options/qualifiers that take an argument may have a trailing equals sign ("=")
Most option/qualifiers can also be specified by their first character.
So the following are equivalent to juke and show
a "plain english", "standard UNIX", or "standard VMS" syntax style:
slot 5
-s 5
/SLOT=5
The code is flexible however, and will also allow the following:
sLoT=5
-slot=5
/SLOT 5
/S=5
