Subroutine invocation

Home Prev Top Next

Use call to invoke a subroutine, followed by the procedure name and parameters, if any.


Call SimpleSub()




Call CompleteSub( "FirstParameter", \$ParamByValue, \$ParamByRef )


Function invocation

To invoke a function (any subroutine that contains a return statement), simply use its name inside an expression. Do not use the call statement to call functions. Example:


\$QName = MakeQualifiedName(\$namespace, "entry")
