5 SEQUENCE INSTRUCTIONS
5.4 Shift Instructions
Shifting n-word data to the left by n word(s)
WSFL(P)
This instruction shifts (n1) words of data to the left by (n2) word(s) from the device specified by (d).
■Descriptions, ranges, and data types
*1 Set so that n2n1.
■Applicable devices
• This instruction shifts (n1) words of data to the left by (n2) word(s) from the device specified by (d). After the shift, (n2)
points from (s) are set into (n2) points from (d).
• This instruction sets the specified value for (n2) points of devices from (d) + (n1-n2) after the shift when K is specified for
(s).
• When the value specified for (n1) or (n2) is 0, the processing is not performed.

Remarks
2820 The (n2) points of data starting from the device specified by (s) exceed in the corresponding device.
The (n1) points of data starting from the device specified by (d) exceed in the corresponding device.
2821 The transfer source data (s) overlaps with shift device (d).
3405 A constant other than K0 or K1 is specified when the constant (s) is specified.
The values specified in (n1) and (n2) are such that (n1)<(n2).
