Subroutine invocation
Use call to invoke a subroutine, followed by the procedure name and parameters, if any.
Call SimpleSub() |
or
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") |
