Setting data Description
(S) to (Sn) Conditional data which controls the flow of program
Processing details
• The block described between CASE and CEND is executed selectively according to the true/false of the data specified with
(S1) to (Sn).
• The true/false evaluation is carried out in order from the top, and the block described between CASE which is first
evaluated to be true and CEND is executed. After that, no true/false evaluation is carried out until SEND, and the next block
of SEND is executed.
• When the data specified with (S1) to (Sn) are all false, the block described from CELSE to CEND is executed.
• CELSE can be omitted. In that case, if the data specified with (S1) to (Sn) are all false, the block between SELECT and
SEND is not executed, and the next block of SEND is executed.
• The following number of CASE(Sn) to CEND can be written between SELECT and SEND
