Respond by entering the slot number containing the memory

card (32K, 64K or 128K RAM board) into which RAMEXPAND is to be

loaded

ENTER TYPE OF CARD YOU ARE LOADING

1= 128K (or 64K)

2= 32K

3= 128K (or 64K) , Language card present

4= 32K, Language card present

Responses:

1. Enter 1 if RAMEXPAND is being loaded into a Saturn 128K

or 64K card and an Apple Language card is not present in the

system.

2. Enter 2 if RAMEXPAND is being loaded into a Saturn 32K

card and no Apple Language card is present in the system.

3. Enter 3 if the system contains an Apple Language card

and RAMEXPAND is to be loaded into a Saturn 128K or 64K board.

4. Enter 4 if an Apple Language card is present in the

system and RAMEXPAND is to be loaded into a Saturn 32K board.

RAMEXPAND is now installed in the system and ready for use.

Two initialization and set—up procedures are generally required

prior to actually moving programs and data into extended RAM by

using the appropriate RAMEXPAND functions.

Before discussing these initialization procedures, the

method of calling and communicating with RAMEXPAND will be desc-

ribed.

B. COMMAND SET-UP

Prior to calling RAMEXPAND, a command must be set up. This

command tells RAMEXPAND what function is to be performed as well

as any necessary parameters. The command must be placed in the

string CM$. RAMEXPAND will always look at CM$ for its command

when called.

The command should contain 5 values, separated by commas.

Each value may be a number or the name of a variable. In several

cases the value must be a variable name. A sample command is as

follows:

CM$ = “A,B,C,D,E”

1 2 ... 26 27 28 29 30 31 32 33 34 35 36 ... 76 77
