Hi,

In a ST, how can I run some part of code only once?

In below example I need to run some part of the code ( commented with ( only once)) only once.

IF a=1 Then

IF b=1 THEN ( only once)
c=1 ( only once)
ELSEIF b=2 THEN ( only once)
c=2 ( only once)
END_IF

CASE c OF 1: ........ ........ 2: ......... .........

END_IF
