 Name:         »Character raw input« - Read a character unbuffered 
               from standard input device.

 Opcode:       7

 Syntax:       int32_t Crawcin ( void );

 Description:  The GEMDOS routine Crawcin reads a character from 
               GEMDOS handle 1 - normally the standard input con: (the 
               keyboard) - without echoing it immediately to the 
               screen or processing any of the 'special' keys.

               Note: The function works correctly with input/output 
               redirection only as of GEMDOS Version 0.15.

 Return value: The function returns a LONG with the ASCII-code of the 
               character in the lower WORD (bits 0 .. 7). If the read 
               character originates from the keyboard, then the lower 
               8 bits of the higher WORD (bits 16 .. 23) will contain 
               the scancode of the keyboard, with Shift-key status in 
               the upper 8 bits provided bit 3 of the system variable 
               conterm is set. Note that if a non-ASCII key is 
               pressed, the ASCII-code returned will be 0.

 Availability: All GEMDOS versions.

 Group:        Character input/output
