/UPPER\LOWER CASE SHIFT FOR THE TYPE "" COMMAND		-JVZ-

/ THIS PATCH PROVIDES A WAY FOR UPPER CASE DEVICES TO PRODUCE
/LOWER CASE OUTPUT BY USING A 'SHIFT' CHARACTER (A BACKSLASH)
/TO TOGGLE BETWEEN UPPER/LOWER CASE. EXAMPLE: T "A\B\C" = AbC
/THIS IS USEFUL FOR INSTALLATIONS WITH AN UPPER CASE TERMINAL
/WHO WISH TO MAKE FULL USE OF THE PLOTTER ANNOTATION ROUTINES,
/OR WHO, PERHAPS, HAVE AN UPPER / LOWER CASE LINEPRINTER.  IT
/SACRIFICES THE CR QUOTE MATCH, SO ALL QUOTED STRINGS MUST BE
/TERMINATED PROPERLY.
