Let's say I have $select->number("MyVariable",$selected,$start,$count,$gapbetween); rather than $select->number($MyVariable,$selected,$start,$count,$gapbetween); If I do a global search and replace on this variable name, using /$MyVariable/ because I have another variable named $NotMyVariable, the string is not matched and is left unchanged. Bad things invisibly ensue. Without contriving other examples (the above is a real one) it appears to me that this capability is symmetric with the $$ notation. This may seem esoterica, but I've bumped into a couple of different instances where I wished I had this - I just can't remember the others. Hey, Hochstaeder (sp?) showed self-reference is good! :O) ("Godel, Escher, Bach - the Eternal Golden Braid" - fun book) G
