This is an interesting point.  The COPY operation is applied during
pass 1 of an assembly, and simply redirects the input to a SYSLIB member.
Thus, there is no such thing as a "conditional COPY".  A consequence
of this is that a COPY is _not_allowed_ to be generated by MACRO.  If a MACRO
generates a COPY the error "IEV001 ... OPCODE NOT ALLOWED TO BE GENERATED"
results.

(To generate a COPY you have to "trick" the assembler by defining a SETC
symbol to be 'COPY' and using it in the opcode field.  If you just put
a COPY inside a MACRO definition the text of the copied member will be
placed _inside_ the definition.)
