Calling a Function
When calling a function where the return is being used, the syntax is:
<variable> = <function_name>([argument_list]);
For example,
INTEGER X, ANALOG1, ANALOG2;
STRING Q$[20], B$[50];
X = ComputeChecksum(Analog1, Analog2);
Q$ = DoSomething(Analog1, B$);
Are legal.
If the return is not going to be used, or there is no return (in the case of a
FUNCTION), the syntax is:
<CALL> <function_name>([argument_list]);
For example,
CALL DoSomethingElse(); (X-Generation or 2-Series)
or
DoSomethingElse() ; (2-Series only)
NOTE: (X-Generation only) Functions do not support recursion, i.e. the code in the
body of a function may not contain a call to that function.
NOTE: The keyword, CALL, is required in the X-Generation control system, and
optional in the 2-Series control system. CALL may not be used when calling non-user
defined functions. For example:
CALL Print( str, “abc” ); // Illegal
