what do you mean context? it only depends on whether the first character after the variablename is a valid character in a variablename or not. if it's valid, use braces. if it isn't, no need for braces.
Arrays can't be used with $array[4], they need to be used as ${array[4]} Also finding the string length, substitution, etc require braces
okay sure. i agree, but we (or atleast i) were (was) talking about regular variables. Dieter
