F99_CMPW

Shifts in data to the smallest address of the specified data table and compresses the data in the table toward the higher address.

Parameters

Input

s (WORD, INT, UINT)

data to be shifted in

Output

d1_Start (WORD, INT, UINT)

starting address of area that is compressed into which data from s is shifted

d2_End (WORD, INT, UINT)

end address of area where data is compressed

Remarks

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

  • Data specified by s is shifted in to the area specified by d1_Start (starting address).

  • 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".

• If the content of s is "0", only a compressed shift is carried out.

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
