F98_CMPR

Shifts out non-zero data stored at the highest address of the table to the specified area and compresses the data in the table to the higher address.

Parameters

Output

d1_Start (WORD, INT, UINT)

starting (lowest) address of data to be compressed

d2_End (WORD, INT, UINT)

final (highest) address of data to be compressed, data at d2_End is shifted out

d3 (WORD, INT, UINT)

receives data shifted out from d2_End

Remarks

The data in the table specified by d1_Start and d2_End is rearranged as follows:

• Contents of d2_End (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_Start and ending area d2_End should be the same type of operand.

• Be sure to specify d1_Start and d2_End with "d1_Start£d2_End".

Error flags

sys_bIsOperationErrorHold (turns to TRUE and remains TRUE)

• if d1_Start > d2_End

sys_bIsOperationErrorNonHold (turns to TRUE for one scan)

• if d1_Start and d2_End are not in the same memory area
