Even though the term of a logical operator is a bit mixed up in the manual, fasm neither casts logical values into numeric values nor it provides operators able to take logical arguments and return a numeric value. You can't use a logical value anywhere except as an argument of if/else if/while/assert or as an argument of one of the 3 logical operators: ~, &, |. In particular you can't multiply a logical value by something.

CandyMan,

To test for non-zero value you may use x or -x bithack:

Code:

rb (($ mod $200) or -($ mod $200)) shr 1 and 128
