|Explanation||PEEKBYTE reports the ASCII value of the
next character waiting on the input stream. The character
is left in the input stream for subsequent READ, READCHAR,
READLINE, READLIST, READQUOTE, or other input
A channel number may be entered as an optional input. If present, PEEKBYTE reads from that channel instead of reading from the input stream. This makes it easier to switch among multiple input streams.
|Examples||The following procedure ignores all
input until a specific character is seen in the input
TO WAIT.FOR :CHAR
