The
command is the beginning of a program or subroutine definition. The syntax for the command is
DEF
followed by 6 or fewer alpha-numeric characters. The first character may not be a number. Refer to the
DEF
command description for information on program size restriction and total number of programs

possible per product.
All programs are stored in a binary fashion within the Gem6K. A program transferred back out (
after it has been defined (

functionally identical.
When defining a program and the memory limitation is exceeded, an error message will
be generated, and bit 11 of the system status register will be set (SS or TSS). The
program will be stored up to the point where the memory limitation was exceeded.
There is no actual difference in the definition of, or execution of a program versus the definition, or
execution of a subroutine. Both a program and a subroutine are defined as the set of commands between a
and an
command. If an invalid program/subroutine name is entered, an error message will be
DEF<t>
END
generated. An invalid program/subroutine name is any name that is also a current command. (An example
of an invalid name would be

The
