OPTEXT SEXP

 Function
  Set the text to be used by the @OPTEXT@ macro.

 Syntax
  OPTEXT str

   str  - Any string expression.

 Remarks
  The @OPTEXT@ macro is used to include operation specific text in
  prompts and display files.  Normally PCBoard automatically fills it in
  with the appropriate value.  However, you can use it for your own
  purposes by issuing this statement to set the text and immediately
  displaying the information that should use it (by either printing a
  line or displaying a file).

 Examples
  OPTEXT STRING(DATE())+" & "+STRING(TIME())
  PRINTLN "The date and time are @OPTEXT@"
  DISPFILE "FILE",GRAPH+SEC+LANG
