Syntax:     INPUT([prompt][,wait][,cnt][,default][,'console'])

Defn: A CI function that writes a prompt and reads an input value
which is functionally return. If "console" is specified the
prompt is written to, and the value is read from the system
console. Otherwise, the prompt is written to $STDLIST and
the input value is read from $STDIN. "wait" is the number
of seconds for a timed read, 0 mean no timeout. "cnt" is
the number of bytes to read. "default" is a string value to
be used as the default response if no input is provided.
The default "prompt" is the null string; default "wait" is
zero; default "cnt" is 1024 characters; default "default" is
the null string; default for I/O is to $STDIN/$STDLIST, not
the console.
