COMMENTS:
If the macro was issued with a label, and the tape name was specified
in a register, this would result in the label being generated twice.
Additionally using the DECB option might cause the label to be created
in the wrong place. Lastly, specifying a label for the location of a
DECB will cause a LGHI being generated, instead of a LA.


SOLUTION:
The macros TPRDC, TOURC and TWRTC macros were changed to check if a
label was specified after all error checking was completed. If a label
was specified a 'DS' statement is generated to create tha label before
any of the generated code. Also the LGHI instruction was changed to a
LA instruction.
