;+ ;FUNCTION: find_handle(name) ; ;PURPOSE: ; Returns the index associated with a string name. ; This function is used by the "TPLOT" routines. ; ;INPUT: name (scalar string) ; name can also be the corresponding integer index to a TPLOT quantity, ; in which case name will be converted to the string handle. ; ;RETURN VALUE: tplot index.
