I I I I I DISABLE ... interrupts
DISABLE switches off all or explicitly specified
interrupts – apart from ON ERROR. If the function
DISABLE ... is used in the main program, it can
prevent interrupts of the corresponding type.
This is particularly useful if a variable, which is set
in an interrupt procedure, is used in in the main
program. To do this you should first switch off the
corresponding (or all) interrupts in the main
program DISABLE ... alter the variable and then
switch the corresponding (or all) interrupts back on
with ENABLE ...
