SECTION FOUR - PREPARATORY FUNCTIONS (G CODES)
This program will clear a pocket that looks like:
Store Restore parameters (G990/G991)
N0020 (My subroutines)
A discussion follows on several specialized and non-standard G codes.
Pp Ll Qq G990 (store parameters)
Pp Ll Qq G991 (restore parameters)
G990/991 allow parameters to be saved and restored using file names C:/RAM/Q0000-Q9999.
Parameters are:
Pp (base parameter number, default 0),
Ll (number of parameters, default 10),
Qq (file identification, default 0).
The G990 and G991 MUST follow the Pp, Ll or Qq.
CAUTION: Have no other commands on the line.
Example:
P0 L10 Q20 G990 (Save parameters P0-P9)

•
(Freely use and modify parameters P0-P9)
•
•
P0 L10 Q20 G991 (restore P0-P9)
M98 (return to caller with original P0-P9)
