INCHRS [TTCALL 2,]
22.63 INCHRS [TTCALL 2,]
FUNCTION
Reads an ASCII character from the job's controlling terminal's input
buffer, skipping on return if a character was available. INCHRS also
sets "character mode," in which the program will not wait for the end
of the line of input from the terminal. Therefore, CTRL/U, DELETE,
and other line-editing characters will not function as they do for the
monitor. See Chapter 15 for more specific information.
