GUIDE

 Function
  Set the display input guide flag in an INPUTSTR or PROMPTSTR statement.
  (Displays "()" above current line for FIELDLEN used and ANSI not enabled)

 Value
  4 = 100b = 4o = 4h

 Remarks
  The INPUTSTR and PROMPTSTR statements have the ability to display the
  length of an input field, regardless of ANSI availability, if you use
  this constant with the FIELDLEN constant.  If ANSI is not available
  and this constant is used, the user will see the input field width
  marked using "(---)" above the input field.

 Example

  STRING pwd
  INPUTSTR "Enter id number",pwd,@X0E,4,"0123456789",FIELDLEN+GUIDE
  IF (pwd <> "1234") PRINTLN "Bad id number"
