An explicit list would be better: {,separator:var1,var2,var3,...} For each variable named in the comma-separated list, if the named variable is defined and non-empty, then substitute the concatenation of variable name, "=", variable value. If more than one substitution is made, separate each substitution with the string of non-colon separator characters between the ',' and ':'. E.g., name = "Fred" age = "41" sex = "" location = "USA" {,&:name,age,sex,location} = "name=Fred&age=41&location=USA" I hope it is clear what the use cases for that would be. ....RoyReceived on Thursday, 2 August 2007 00:32:15 UTC
