Totally agree.

>>The gist of the argument was essentially that the m. construct was not necessary and, in some cases, less efficient. For instance, when assigning values to a var, it's no use in distinguishing between a table field and a memory var of the same name, because one always uses "REPLACE" for fields anyway. Of course, if there are a field and var of the same name (and assuming the field's table is currently selected anyway) then it is useful for distinguishing in cases of comparison. But that's the only advantage I can see.

>>I recall the m. as a throw-back to the old dBASE days and, personally I never use it. Does anyone have an argument for its use? Can anyone put their finger on the article to which I referred?
