74 FUNC EDIT = Edit System Ram

FUNC EDIT = Edit System Ram


System memory space can be seen and
altered using a FUNC version of EDIT. System
memory space is where the working program is
stored when loaded from a LIBRARY ROM, in
the Transient Program Area which extends
from 8000 to FFFF. If the FUNC key is pressed
from the command prompt, the prompt
changes from a >> to a *. EDIT then works on
system memory. The LCD behaves exactly as
the normal edit routine.

WARNING *EDIT allows changes to the
working program and system variables. S4
can be crashed by editing the running
program, if indiscriminate changes are
made to the stack or code. Regard the TPA
as a "NO GO" area unless you are certain of
what you are doing. You can recover from
any changes by pressing the RESET button
and reloading the LIBRARY ROM.
