SUMMARY

The PROW() function is used to return the current row position of the printer. This function can be useful when you are trying to relatively address printer output. However, even if SET PRINT OFF is issued, issuing an @ ... SAY command will change the value returned by PROW().

   SET PRINT ON
   SET DEVICE TO SCREEN
   EJECT

   ? PROW()                      && Returns 0.

   SET DEVICE TO FILE test.txt   && Output to a file.
   SET PRINT OFF                 && Printer is disabled.
