N. Create MEM.SAV*
The Create MEM.SAV operation is used to create a MEM.SAV file
on the diskette in drive 1.
Whenever DOS version 2.0 is booted, the DUP.SYS disk file will
overwrite an area in memory where BASIC programs are stored.
When a MEM.SAV file is present on the diskette in drive 1, the
computer will transfer all data present in the memory area used
by DUP.5YS
int o the MEM.SAV file. Afterwards, DUP. SYS will be
loaded, and
the DO S menu will appear.
When you have finished us ing DOS, by ente rin g the
Run Cartridge operation, the program in MEM.5AV will be
automatically loaded
from MEM .SAV into RAM.
When a MEM.SAV file is used, more time will be required to load
the
DOS menu. Illustrat ion 7-16 depicts the use of Create
MEM.5AV.
