SUMMARY

The MS-DOS 5.0 "User's Guide and Reference" and MS-DOS 6.0 "User's Guide" do not show a second parameter for the FCBS command. The online Help for MS-DOS 6.0 and 6.2 also does not show this parameter.

In previous versions of MS-DOS, the second FCBS parameter set the number of files opened by FCBs (file control blocks) that MS-DOS cannot close automatically. This parameter is no longer necessary with MS-DOS 5.x and later due to the nature of the new FCB scheme.

When MS-DOS 5.x and later versions parse the CONFIG.SYS file, it disregards a second parameter if present on the FCBS line. This feature allows old style FCBS commands to be processed without error under MS-DOS 5.x and 6.x.
