On Fanuc 21i-TB is there a parameter number to lock the common variables #500 to #531 so they can not be changed or deleted?

Not That I'm Aware of...I ussually store them in a 8000 or 9000 series program and then lock those programs, and use a sub program call to reload the variables before I need them ...Just incase anybody changed anything they will always get reloaded....

example:
O0001(main program)

M98 P9000

"progam needing variables"

M30
%

O9000(VARIABLES LIST)
#500=??
#501=??
#502=??
etc.
M99
%

param 3202 bit 4 (NE9) locks 9000 series and bit 0 (NE8) locks 8000 series programs...
