Memory
This screen helps the user allocate the AC
R’s available memory to programs, global variables and Defines.
The
memory allocation (in bytes) can be altered in the
Value
column. The
Allocation
bar at the bottom of the screen
shows how much memory is used and how much is free.
Memory for programs has already been allocated.
Only if the programs are very large (notified on
download) would these allocations need to be
increased. Program memory is consumed by
AcroBASIC code, locally dimensioned variables,
program statements with returns (
GOSUB
,
IF
,
WHILE
and
FOR
statements) and interpolated
moves (e.g.
X3 Y7
).
Program 14 has a large allocation for the onboard
data capture for scopes. The Configuration Wizard
settings are stored within Program 15, which has a
fixed allocation.
By default, the number of global variables is 4096
(P0
—
P4095). These are 64-bit floating point values
available to the user for any use. They are not
retained by default, but their values can be saved to
flash using the
FLASH IMAGE
command. It is
recommended to leave this allocation at default.
The memory for defines is also set here. By default, the user is given 100 Defines. This is sufficient for many
applications, but some may need more. If more are required, the allocation must be increased and the
