GOSUB label

    or

CALL label

[CALL]  function/sub

CALL ( expr )

GOSUB is supported for backward compatibility, now FUNCTIONs and SUBs and their implied CALL would be a preferred method.

Execution jumps to a subroutine marked by line label. Always use RETURN to exit a GOSUB, execution will continue on next statement after Gosub.

label may be defined as label: or as a SUB or FUNCTION

CALL for a FUNCTION or SUB is optional.  When CALLing a FUNCTION the return value is discarded.

CALL (expr) was added in 7.40 compiler which allows calls to a pointer to a function.  The first right parenthesis is required.  Parameter passing to this type of call is not supported.

• CALL used in Visual BASIC and version 7.00 makes the CALL optional for FUNCTION/SUB like VB
• GOSUB used in PBASIC

• GOTO
• RETURN
