INPTMR.DOC - DOCUMENTATION FOR INPTMR.SBR 1.1B(110)
               NOTE: you must XCALL NOECHO before using this routine!
USAGE:  XCALL INPTMR,STRING-VARIABLE,FLOAT-VARIABLE
       ...where:
               STRING-VARIABLE is the variable to put characters in
               FLOAT-VARIABLE is seconds to wait after last character
               (if FLOAT-VARIABLE is negative, chars will not echo)
Subroutine will return with one of these conditions:
       a) you filled STRING-VARIABLE with chars.  FLOAT-VARIABLE now contains
          number of chars typed.  (subroutine looks at MAP to get length)
       b) you typed some chars and a [c/r].  FLOAT-VARIABLE now contains the
          number of chars typed, not counting the [c/r].  (If only [c/r], =0)
       c) you exceeded the time in FLOAT-VARIABLE.  You may or may not have
          typed some characters, but did not press [c/r].  Any chars are
          still in STRING-VARIABLE, but FLOAT-VARIABLE now contains a -1 to
          indicate a timed-out condition.
       d) you typed a ^C.  FLOAT-VARIABLE contains a -1, and routine exits.
