According to Sofistik manual pp9-9

& | Bitwise logical operation on the integer part with AND or OR

+PROG Template
LOOP#i 3
IF #i==0
LET#List(#i) -1
ELSEIF #i==2
LET#List(#i) -1
ELSE
LET#List(#i) 1
ENDIF
ENDLOOP
PRT#List
end

The result is -1,1,-1, which is I expected.

But if I use
+PROG Template urs:1
LOOP#i 3
IF (#i==0|#i==2)
LET#List(#i) -1
ELSE
LET#List(#i) 1
ENDIF
ENDLOOP
PRT#List
end

The result is 1,1,1, which is not I expected.
How to use “|” in “IF” condition?

See adjusted code below:

+PROG Template urs:1
LOOP#i 3
IF (#i==0)|(#i==2) $ This fixes it
LET#List(#i) 12
ELSEIF #i==2 $ this is unnecessary, since the first condition kicks in
LET#List(#i) 2
ELSE
LET#List(#i) 1
ENDIF
ENDLOOP
PRT#List
end
