'''4OS2''' is the OS/2 analogue of [[Software:Take Command Console|4NT]] and [[Software:4DOS|4DOS]] by JP Software, Inc.  JP Software discontinued 4OS2, TCMDOS2 and TCMD16, making version 3.0, 2.0, 2.0 the final version of these.  The code for 4OS2 has been released, and is maintained, first by [[Company:SciTech Software|SciTech]], and then by NetLabs.

==Overview==
Early versions of 4OS2 run in the [[Software:Windows NT|Windows NT]] OS/2 emulation, and it was this particular running that lead JP Software to port 4OS2 to [[Software:Microsoft Windows|Microsoft Windows]].  4NT, for example, still has the OS/2 [[Software:Cmd.exe|CMD.EXE]] commands like EXTPROC and REXX support, while earlier versions had commands like [[Software:Dpath|DPATH]] and [[LIBPATH]], for setting these variables in the same manner that PATH does.  

The early 4OS2 packages came with both 16- and 32-bit versions, the former to run under OS/2 1.x including Windows NT OS/2. Eventually the 16-bit support was dropped.

JP Software have their final releases of these products at their download page.<ref>http://www.jpsoft.com/download.htm</ref>

There was a 4OS2 v4.0 as different programmers took up maintaining the release, but these have been since merged.<ref>http://www.4dos.info/v4os2.htm</ref>

4OS2 has found more recent life at NetLabs.<ref>http://4os2.netlabs.org/en/site/index.xml</ref>
