■ SUBMAINPROG .. ENDPROG
The code word SUBMAINPROG begins the sub-
routine section, and the code word ENDPROG
ends this specific program. The term subroutine
means command sequences that, via the GOSUB
instructions, can be called up and executed from
various program positions.
All necessary subroutines must be contained within
the subroutine section. It is possible to insert a
subroutine anywhere within a main program; how-
ever, for reasons of clarity, it is advisable to insert it
either at the beginning or end of a program.

■ SUBPROG name .. RETURN
The instruction SUBPROG identifies the beginning
of a subroutine. The name of the subroutine must
directly follow SUBPROG code word. The name
can be made up of one or more characters, and
must be unique, i.e. only one subroutine may have
that name.
A subroutine can be called up and executed at
any time by use of the GOSUB instruction.
A subroutine can have any number of command
lines and can refer to all program variables. The
last command in each subroutine must be the
RETURN instruction, which permits exiting the
subroutine and continuing the program with the
command following the GOSUB instruction.
