Does this opcode stuff come into play on the outside where we write code. Please provide an example. Thanks.

This implies that there are in fact two seperate types of variables. If you inquire into the frame where the variable map is being stored as it's running (workspace not object code) you will see that yes a string variable starts with a 09 and a numeric I forgot I think its a 01 or 02 ... > At any rate, its not stored as a string while running, but rather I believe its probably stored based on whatever the last action was on it. A numeric action returns a numeric value and is stored as a numeric. A string action like concatenation would probably switch it to be stored, at that moment, at any rate, as a string. I didn't test *this* behaviour explicitly, so I'm not quite sure. > Will > > > In a message dated 2/6/2004 3:29:01 PM Eastern Standard Time, [EMAIL PROTECTED] writes: > > > > > It's been affirmed here and other places that MV considers everything as > > a text variable (keep file handles and arrays out of this > > discussion) and > > its numerological properties come > > > > into play only when we expect it to behave as a number. > -- > u2-users mailing list > [EMAIL PROTECTED] > http://www.oliver.com/mailman/listinfo/u2-users -- u2-users mailing list [EMAIL PROTECTED] http://www.oliver.com/mailman/listinfo/u2-users
