)VARS (first (last))

Lists the names of all global variables in the current workspace. If the command is followed by a character or group of characters, the list gives the names of all variables beginning with that character or group of characters onwards (the parameter first, used on its own). A second character or group of characters after the command (the parameter last) is used to end the list of names. Names are shown in alphabetic order, fully sorted.
