RE: How to create my own built-in functions

[Scott Klement <klemscot@xxxxxxxxxxxx>]

In Buck's examples, "RC" was the variable that he "returned".  (It had
nothing to do with the length of the parameters)

When you code a statement like

C                   eval      Result = MySubProc('something')  

the "returned value" is the value that will be assigned to Result.  

So if MySubProc ended with:
c                   return    50   

then (back to the example above) Result would be set to 50.

If MySubProc ends with:
c                   return    RC

Then Result will be assigned whatever value was in the variable "RC" at
the time that the return statement was executed.

Actually, there was a rather silly bug in Buck's code...  he had his
return type defined as "10u 0"  (an unsigned integer) but he was sometimes
returning -1, which is a signed value... :)
