____________________________________________________________________

This is a complement to the ISaGRAF Language Reference Guide,

concerning IL language.

The "N" modifier can be applied to "JMP" and RET" instructions, but

only in the case where these instructions are already touched by the

"C" modifier. Below is the exact list of valid combinations:

JMP jump always

JMPC jump if current result is TRUE

JMPCN jump if current result is FALSE

JMPNC same meaning as JMPCN

RET return always

RETC return if current result is TRUE

RETCN return if current result is FALSE

RETNC same meaning as RETCN

The instructions "JMPN" and "RETN" are not valid.
