I am trying to use a cobol switch (what is called an UPSI switch in IBM)
for the first time on HP and must be doing something incorrectly. I
have entered the following under special names:

SW0 IS SORT-SWITCH ON IS SORT-BY-SUBJECT

In the program logic, the following is coded:

IF  SORT-BY-SUBJECT
    (DO THE SORT BY SUBJECT)
ELSE
    (DO THE SORT ANOTHER WAY).

In the run statement is the following:

RUN WRT001O.SMC.COLLEGE;PARM=%1000000

Can you see anything wrong here?
