5.4.4 Using XRAM and EPROM Programs as Subroutines
The BASIC programs are limited to the size of program that you can squeeze
into XRAM. However, you can create larger programs by using CALLs 70, 71,
and 72. These three CALLs allow you to use XRAM and EPROM programs as
subroutines.
5.4.5 Automatically Executing ROM 1 at Power-up
If the setup jumper is off, then the program in XRAM will automatically be
executed at power-up. You can change the module to automatically execute
ROM 1 at power-up by using the PROG2 command. The PROG2 will have the
same effect at power-up as someone typing RROM 1 (or ROM 1, RUN). If at a
later time you want to stop executing ROM 1 at power-up, use PROG0 to clear
the effect of PROG2.
