# PREVIEW

> [HTML Version](previewptrini.htm)

**PREVIEW = <Boolean>**

This option forces the SSW\_PREVIEW flag (524288 or \&h80000) to be set in the switches, provided that the SSW\_NOPREVIEW flag (1048576 or \&h100000) has not already been set. This is equivalent to passing the /PREVIEW switch to PRINT.LIT, or setting the SSW\_PREVIEW bit in the switches parameter to XCALL SPOOL.
