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
