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.
