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.
