Syntax for argument with '|' seperator


for a procedure I need the possibility to combine two arguments with a OR character.
With optional arguments it works fine, but I don't wanna use optional arguments.

The following code is not accepted.
PROC SetValue(num Value<b>|</b>dnum Dvalue)

I want the independence of the data type for calling SetValue.
VAR num Value;
VAR dnum Dvalue;

SetValue Value;<br>SetValue Dvalue;<br>

I found a code example in the manuel for the procedure SetGo.

This is the syntax from the robotware manuel "technical reference manual - RAPID Instructions, Functions and Data types" on page 688.
[ '\' SDelay ':=' < expression (IN) of num > ',' ]
[ Signal ':=' ] < variable (VAR) of signalgo > ','
[ Value ':=' ] < expression (IN) of num >
| [ Dvalue' :=' ] < expression (IN) of dnum > ';'

I hope someone can help me.

Thanks in advance!


  • Hello,

    We've looked into this and because RAPID does not support overload you'll have to 'normalize' the variable before you call the function. With normalize I mean convert to either num or dnum.

    Consult the RAPID manual on how to do the conversion.

    Interesting question! So, what kind of magic does the SetGO function have behind the scenes that it's able to do the num or dnum without conversion?
  • Hello Maxim Riabichev,

    thank you for your response!

    I know the conversion function, but from a programmer's point of view it would be fantastic if two non-optional arguments could be combine with "or". 

    The SetGo command illustrates the advantages!

    I think it would be great if this possibility would be added in a future robotware update.
  • Hello,

    Okay I'll have a talk with my collegues tomorrow.

  • Hello,

    So we've spoken about this matter and we've reached the conclusion that the best would be if RAPID would support Overload, like C# does for example.

    I will move this thread to the UpFeed section (as a suggestion for future addition to RAPID).
