Explanation

The $LEN function in IDEAL returns the defined length of a field, not its actual content length. W01_VAR is defined as X(6), meaning it has a fixed length of 6 characters regardless that it contains 'IDEAL' (5 characters). The $LEN function returns 6 because that's the defined length of the variable. The LIST command displays this value.
