Description

The SET DEVICE TO PRINT command sends the output from @...SAY commands to the printer. After this command has been issued, the PROW() and PCOL() functions return the current row and column position of the print head on the printer, and the ROW() and COL() functions return undetermined values. When DEVICE is set to PRINT, @...GET commands are ignored.

The SET DEVICE TO SCREEN command sends the output from @...SAY commands to the screen. After this command has been issued, the ROW() and COL() functions return the current row and column position of the cursor on the screen, and the PROW() and PCOL() functions return undetermined values.

The SET DEVICE TO FILE command directs @...SAY commands to a file specified by <filename>.

By default, SET DEVICE is set to SCREEN, which is the normal mode of operation.
