IO_Edit                                                          IOTTT



Purpose   To control user input of data.

Type Mandatory.

Declaration    IO_Edit(var Retcode: integer);

          Retcode must be an integer variable

Uses CRT, FastTTT, DOS, WinTTT, KeyTTT, IOTTT.

Remarks   When you have declared all the parameters and defined all
          the IO procedures (including any optional procedures such as
          color changes) then you're ready to let the user input and
          update the fields. IO_Edit does this and passes control to
          the user.

          The procedure returns control to your program when the user
          has ended the update session, either by pressing End or Esc
          (if it is enabled) or by pressing any of the move to next
          field keys (Enter, Tab, etc.) when the next field has been
          defined as ID zero.

          The Retcode variable is updated with a return code for the
          edit session. The return codes are :

               0 for successful completion
               1 if user pressed Esc key

!IO_ResetFields          Dispose of menory used during IO & reset input variables
IO_ResetFields                                                   IOTTT



Purpose   To dispose of memory used during IO process and reset the
          input variables to default values.

Type Mandatory.

Declaration    IO_ResetFields;

Uses CRT, FastTTT, DOS, WinTTT, KeyTTT, IOTTT.

Remarks   This procedure is normally the next statement after IO_Edit.
          It discards all the field definitions from the Heap and sets
          all the optional settings (such as color) back to the
          default values.
