The problem is the variable size of the result. The first record which Visual FoxPro finds, in this case, might not fulfil the condition in the IIF(), and, therefore, return 0 (size: 1 byte). Then, VFP decides that this is the correct size for the rest of the table - and you get the asterisk (which means, "the result does not fit").

In general, you should avoid variable-sized results in a SELECT - SQL command - or at least make sure that the minimum size of a field is big enough.

Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
