PMODE is a DOS extender used in several IBM PC compatible DOS applications in the mid and late 1990s. It was created by , and the first version became publicly available in 1994. The original PMODE was written to be used with programs written in x86 assembler, specifically using Borland's TASM. It was later expanded for use as a drop-in replacement for DOS/4GW under the name PMODE/W. As of 2002, PMODE/W may be freely used in commercial software, provided the software is not itself a DOS extender.
