RE: Benefits of Sub-procedures

There is a tool out there that will convert all subroutines into
subprocedures. This is useful in some situations, just watch out though...
if the subroutine contains a RETURN opcode, it will return to the calling
program. If that subroutine is migrated to a subprocedure, the RETURN opcode
simply returns to the caller of the subprocedure (i.e., the mainline calcs
or another subprocedure).

Not sure whether I was misinterpreted.  I was intending to extend your idea
of
forgoing all subroutines "for two to three months just to get into
practice." 
Sometimes I need to be "coerced" like that.  <g>

By the BTW:  Enforcing this "no subroutines" idea would almost have to take
into
account existing apps that have myriad SR's.  The pre-compiler option could
look at
the source statement mod date and kick out those with a higher date than... 

Like I have nothing better to do.   <g>
