Re: Ending a program from within a procedure

Kurt,

My two cents.

A subprocedure has no business controlling the flow of anything that calls
it.  It's a poorly designed procedure if it forces any caller into behavior
that isn't really wanted.  You may be writing both the caller and the
subprocedure but what if some other programmer wants to lift your
subprocedure code for use in another program?  You're just asking for
trouble.  Instead of ending the program the procedure should notify the
caller then let the caller decide what to do with the error.

Have the procedure return one value.  If it needs to return more than one
value pass the rest as non-const parameters to the procedure.  In this case
I would return the indicator as the result value and pass the variable that
is also to be returned as the last parameter in the procedure call.
