Mark, Another one just bit me. Take this command
command TestItems svar1 , svar2 , svar3 put "*" & item 1 of svar2 & "*" end TestItems Now call it like this: TestItems 1, 3 ,2 Yields "*3*" TestItems 1,,2 Yields "**" But what I did NOT expect is.... TestItems 1, ,2 Yields "* *" TestItems 1, ,2 Yields "* *" Now why would extra spaces between parameters become spaces??????? This just move to the top of the bite-an-LC-newbee list for me!
