Lew, &memvar is NOT the same as "&memvar." The former simply replaces the &memvar with the characters you specify in memvar and this will NOT end up being a string as far as VFP is concerned in the code A couple of examples:
Example 1 --------- Hello="Newval" cStr1="Hello" cStr2=&cStr1. && Gives cStr2 as "Newval" cStr2="&cStr1." && Gives cStr2 as "Hello" Example 2 ------------- Memvar="Select *" &memvar. From Customer into cursor curTest This simply builds theSQL expression but you could use exec() which is quicker =Exec(Memvar+" From Customer into cursor curTest") Example 3 --------- Memvar="Fred" Replace Name with "&Memvar." in Customer This is of course the equivalent of: Replace Name with Memvar As a matter of course I always terminate a macro with a "." because it makes the macro expression stand out expecially if you are accessing an object as the Macro value: Memvar="oObject" vValue=&Memvar..Property1 However It is preferable and quicker to use the Eval() in these circumstances i.e vValue=Eval(Memvar+".Property1") Hope this helps Dave Crozier "A computer is a stupid machine with the ability to do incredibly smart things, while computer programmers are smart people with the ability to do incredibly stupid things.

Eg if a macro is stored in a memvar, instead of seeing: &memvar The code consistently reads: "&memvar." All I can find out about this is that the programmer decided that using the quotation marks and dot all the time avoided problems. Anyone have any idea what problems are being addressed here, if any? -Lew [excessive quoting removed by server] _______________________________________________ Post Messages to: ProFox@leafe.com Subscription Maintenance: http://leafe.com/mailman/listinfo/profox OT-free version of this list: http://leafe.com/mailman/listinfo/profoxtech ** All postings, unless explicitly stated otherwise, are the opinions of the author, and do not constitute legal or medical advice.
