Re: prototypes and functions

[Rob Berendt <rob@xxxxxxxxx>]

One little thing though.  If you plan on using service programs in 
the near future, you might want to consider using /copy for your 
prototypes which may be used in more than one program.

Subject:        prototypes and functions

Actually, this post explained it quite well, and gave me all the pieces I
need to put my own together.  It is basically the same as in any
programming language, such as VC++, VB, Delphi (Pascal), etc...

The pieces in all these languages are this:
1. Give a prototype of the function to be called, including all the
   parameters to be passed, and any returning parameters.  Put
   this at the top of the program so it is one of the first lines found.
2. Code the main program, calling the procedure as needed.
3. Code the function, giving the parameters to be passed (once
   again, yes, this is done twice) and any return parameters.
4. Code any local variables to be used in the function
5. Code the logic
6. Code the return value

3 through 6 are, in effect, a program unto them selves.  They just
reside in the main source file.

1 is done to allow the compiler to perform as few passes as possible.
It is not done for us, but for the compiler.  So it knows what the
function is going to look like when it hits a call to it in the main line.

This is an excellent boiler plate, thanks a lot! It gives me all the pieces
I need.

Jim Langston
