Intrinsic-7 ChIn

7: variable:= ChIn(device);


This intrinsic reads in one byte from the specified input device. The byte is usually an ASCII character (hence: CHaracter IN), but it can be any 8-bit value. After the character is read in, ChIn is ready to read the next character. For example:


       X:= ChIn(0);                \Get byte from keyboard buffer
