PROCEDURE KeyPressed() :BOOLEAN;
(*
Is there a character waiting?
*)
PROCEDURE GetKey( VAR k :CHAR );
(*
Like BASIC INKEY.
Returns either a character or a 0C and the extended character code
on the next call.
*)
PROCEDURE GetKeyCh( VAR ch :CHAR );
(*
Extended character codes are remapped into the upper 128 ascii codes
as by the constants declared above.
*)
PROCEDURE GetFunKey( VAR ch :CARDINAL );
(*
This call added to support international character sets that use the
upper bit of a CHAR.
The ordinal value of regular characters is returned.
Extended character codes are remapped into the upper 128 ascii codes
as by the constants declared above but, then, 100H is added to the
result.
For Example, F1 would be returned as 01ADH
*)
PROCEDURE GetShiftStatus( VAR st :ShiftStatus );
(*
Gets the status of shift/control keys.
