Re: Crashing on DEQU

Hi Martin,

Space(10) returns a String with 10 characters ( ten times CHR(32) )

? Space(10) == "          "       // TRUE  (with 10 CHR(32) )
? Space(10) == "   "             // FALSE
? Space(10) == NULL_STRING // FALSE
? Space(10) == "ABCGE "         // FALSE
? Empty(Space(10))                 // TRUE
? Space(10) == 25                    // Compiler error

If you look to the code above, you will find that the comparison may be 
ambiguous.

regards
Urs
