2.6 Subroutines
A subroutine is a set of instructions with a particular name or a line label.
User can simplify their programming by breaking programs into
subroutines. A subroutine will be executed when being called by a
GOSUB command.
For example:
ON COM (1) GOSUB ReadCOM
…
ReadCOM:
…
RETURN
The command RETURN marks the end of the subroutine and tells the
processor to return to the caller. A subroutine has to be appended at the
end of the main BASIC program. A subroutine can be defined with or
without a pair of brackets.
For example:
GOSUB FUN
GOSUB Place
GOSUB Test
END
…
SUB FUN( )
PRINT "Run function!!"
END SUB
