F98_CMPR
Shifts out non-zero data stored at the highest address of the table to the specified area and
Description
compresses the data in the table to the higher address. The data in the table specified by d1 and
d2 is rearranged as follows:
Contents of d2 (highest address) are shifted out to the area specified by d3.

Non-zero data is shifted (compressed) in sequential order, in the direction of the higher address in
the specified range.

 Starting area d1 and ending area d2 should be the same type of operand.
 Be sure to specify d1 and d2 with "d1  d2".
This instruction also exists as a P instruction (for FP2/2SH, FP3/5, FP10/10SH PLC types), which
is only executed at the rising edge of the EN trigger. Select [Insert P instruction] from the
"Instructions" pane if you require a P instruction. To facilitate reuse, the instruction then appears
under "Recently used" in the pop-up menu. Press <Ctrl>+<Shift>+<v> within the programming
area to open the list of recently used elements.
