USER MANUAL

The total macro memory requirements can be calculated by summing the

memory for each individual macro. For example, suppose that you use one

macro

to connect secondary #7, another macro to issue a Primitive 45 bytes long

expecting

a response 30 bytes

long, and another macro to disconnect secondary

#5.

The total memory required for these three macros is:

Macro #1, Connect

= 22 = 22

Macro #2, Primitive

= 22 + 45 + 30

= 97(+1)

Macro #3, Disconnect

= 22 = 22
