Hi!

For me it appears as a defect. The most stranmge is that built-in VFP functions are accepted by type() function correctly, for example:
? TYPE("alltrim('00023')")
returns correct value "C".

Well, I see you found a solution alredy < s >. BTW, you can mark your own message as answer to the thread :-)
