variable
A DSE instruction is like a FOR–NEXT loop with a negative increment.
After pressing a shifted key for ISG or DSE (
z k
or
{ m
), you
will be prompted for a variable that will contain the loop–control number
(described below).
The Loop–Control Number
The specified variable should contain a loop–control number ±ccccccc.fffii,
where:

±ccccccc is the current counter value (1 to 12 digits). This value changes
with loop execution.

fff is the final counter value (must be three digits). This value does not
change as the loop runs.

ii is the interval for incrementing and decrementing (must be two digits or
unspecified). This value does not change. An unspecified value for ii is
assumed to be 01 (increment/decrement by 1).
Given the loop–control number ccccccc.fffii, DSE decrements ccccccc to
ccccccc — ii, compares the new ccccccc with fff, and makes program
execution skip the next program line if this ccccccc
≤
fff.
Given the loop–control number ccccccc.fffii, ISG increments ccccccc to
ccccccc + ii, compares the new cccccccc with fff, and makes program
execution skip the next program line if this ccccccc
>
fff.
