SUBROUTINE SYMSS (UC,LC,OVER) C$ (Switch Select) C$ Define two Hollerith characters, "UC" and "LC", for C$ switching from lower to upper-case, and upper- to C$ lower-case, respectively, and a single Hollerith character, C$ "OVER", for overstriking the last character position. A C$ blank or zero value should be provided for any of these C$ which are not intended to be specified. C$ C$ The switch characters apply to the current Hershey font, C$ which must have been selected before calling this routine. C$ Case switch characters apply only if an upper-case font has C$ been selected, since with a lower-case font, all letters C$ are mapped into lower-case. It may be convenient and C$ easily-remembered to use UC = 1H< (left angle bracket), and C$ LC = 1H> (right angle bracket). A switch character which C$ appears twice in a row will be collapsed to a single C$ character, and not recognized as a switch character. C$ (02-FEB-82)
