SMC_ReadNCTokens.StepSuppress (ACT)

We encode a leading ‘/’ character into the line number of the first ‘N’-word: 1) if the original value is positive, it is negated 2) if the original value is 0, the least negative value is used Note: the least negative value of a DINT is -2^31, the greatest positive value is (2^31 - 1), so negating a positive DINT can never result in the least negative value.
