INT 2F U - DOS 4.x only SHELLB.COM - SHELLC.EXE INTERFACE AX = 1901h BL = SHELLC type 00h transient 01h resident DS:DX -> far call entry point for resident SHELLC.EXE Return: ES:DI -> SHELLC.EXE workspace within SHELLB.COM Note: SHELLB.COM and SHELLC.EXE are parts of the DOS 4.x shellTop
INT 2F U - DOS 4.x only SHELLB.COM - COMMAND.COM INTERFACE AX = 1902h ES:DI -> ASCIZ full filename of current batch file, with at least the final filename element uppercased DS:DX -> buffer for results Return: AL = 00h failed, either (a) final filename element quoted at ES:DI does not match identity of shell batch file quoted as parameter of most recent call of SHELLB command, or (b) no more Program Start Commands available. AL= FFh success, then: memory at DS:[DX+1] onwards filled as: DX+1: BYTE count of bytes of PSC DX+2: N BYTEs Program Start Command text BYTE 0Dh terminator Desc: COMMAND.COM executes the result of this call in preference to reading a command from a batch file. Thus the batch file does not advance in execution for so long as SHELLB provides PSCs from its workspace. Note: The PSCs are planted in SHELLB workspace by SHELLC, the user menu interface. The final PSC of a sequence is finished with a GOTO COMMON, which causes a loop back in the batch file which called SHELLC so as to execute SHELLC again. The check on batch file name permits PSCs to CALL nested batch files while PSCs are still stacked up for subsequent execution.Top

INT 2F U - DOS 4.x only SHELLB.COM - SHELLB transient to TSR interface AX = 1904h Return: ES:DI -> name of current shell batch file: WORD number of bytes of name following BYTEs (8 max) uppercase name of shell batch fileTop
INT 2F U - DOS 5+ - COMMAND.COM INTERFACE AX = 5500h Return: AX = 0000h if an instance of COMMAND.COM is already running DS:SI -> entry point table Notes: used to access the shareable portion of COMMAND.COM, which may have been moved into the HMA; only the primary COMMAND.COM retains this portion procedures called from a dispatcher in COMMAND's resident portion; most assume that the segment address of the resident portion is on the stack and are thus not of general use DR PalmDOS up to DR-DOS 7.03 COMMAND.COM do not support this call. When loading the default command processor (no SHELL= directive in CONFIG.SYS), MS-DOS 6.0-6.22 IO.SYS & PC DOS 6.1-2000 IBMBIO.COM check a signature (see #04099) in the COMMAND.COM file image to test if it is actually their own shell and has the correct version, before they will launch it. If the signature is not found, the message "Invalid COMMAND.COM" will be displayed. This test seems to have vanished with MS-DOS 7+, as it uses an .EXE style file format. In addition to this, the MS-DOS/PC DOS COMMAND.COM checks the version of the underlaying OS to see if it is their own. Hence, the PC DOS 6.1 (and by SETVER version faking also the PC DOS 7 and 2000) COMMAND.COM also run on Novell DOS 7 - DR DOS 7.03, which all identify themselves as DOS API level 6.0 and IBM OEM (not yet tested as primary shell). PC DOS 5.0 COMMAND.COM should run on DR PalmDOS (untested). The MS-DOS 7+ COMMAND.COM seems to no longer perform this kind of version check any more, which can cause a serious deadlock situation on a multi-boot system with DR-DOS installed, when the MS-DOS 7+ COMMAND.COM is placed in C:\. When IBMBIO.COM attempts to load the MS-DOS 7+ COMMAND.COM as a primary shell under DR-OpenDOS 7.02 to DR-DOS 7.03 no error message will be displayed by COMMAND.COM, but the machine will just hang. To defuse this situation, DR-DOS 7.02+ IBMBIO.COM was changed to still scan for a SHELL= directive in [D]CONFIG.SYS even in F5-mode. For maximum safety, the MS-DOS 7 COMMAND.COM should be moved from C:\ to C:\WINDOWS\COMMAND\ and a DCONFIG.SYS file should be created containing for example SHELL=C:\DRDOS\COMMAND.COM instead. If a MS-DOS CONFIG.SYS file exists, it should contain a SHELL=C:\WINDOWS\COMMAND\COMMAND.COM directive. (If no shell can be found at all, DR-DOS IBMBIO.COM would display a prompt to enter the proper path to COMMAND.COM). The DR-OpenDOS 7.02+ COMMAND.COM is designed to also run on 3rd party operating systems like MS-DOS/PC DOS 3.31+, Windows 9x, and in DOS boxes of OS/2, Windows NT and 2000, and will for example also take advantage of long filenames. SeeAlso: AX=5501h Format of Microsoft COMMAND.COM file image signature: Offset Size Description (Table 04100) 00h 3 BYTEs E9h xxh xxh (JMP instruction) 03h BYTE version bits 7-4: major version bits 3-0: minor version code ( 60h for MS-DOS 6.0 and PC-DOS 6.1; 64h for MS-DOS 6.20, Japanese MS-DOS 6.2, Hangeul MS-DOS 6.2; 66h for MS-DOS 6.22, PRC (Chinese) MS-DOS 6.22; 70h for PC DOS 7, PC DOS 7 Y2K edition ) Notes: Since DR DOS 6.0+, MS-DOS 7.0+, PTS-DOS, S/DOS, 4DOS/NDOS use an .EXE style shell file format, this signature is not met by any release of these shells. DR DOS 3.31-5.0 used a different jump (E8h) at offset 00h. Older releases of MS-DOS/PC DOS all had a jump (E9h) at offset 00h, but other values at offset 03h. For reference here is a list of the values for some of these older shells: 00h for PC DOS 1.10, Olivetti DOS 2.11, MS-DOS 5.0, Russian MS-DOS 5.0 1Eh for MS-DOS 4.01 BAh for PC DOS 3.10, 3.20, MS-DOS 3.30Top

Return: AL = FFh if this command is a TSR extension to COMMAND.COM
AL = 00h if the command should be executed as usual
Notes: This call provides a mechanism for TSRs to install permanent
extensions to the command repertoire of COMMAND.COM. It appears
that COMMAND.COM makes this call before executing the current
command line, and does not execute it itself if the return is FFh.
APPEND hooks this call, to allow subsequent APPEND commands to
execute without re-running APPEND

INT 2F U - DOS 3.3+ internal - INSTALLABLE COMMAND - EXECUTE AX = AE01h DX = magic value FFFFh CH = 00h CL = length of command name (4DOS v4.0) DS:BX -> command line buffer (see #02977) DS:SI -> command name buffer (see #02978) Return: DS:SI buffer updated if length byte is nonzero, the following bytes contain the uppercase internal command to execute and the command line buffer contains the command's parameters (the first DS:[SI] bytes are ignored) Notes: this call requests execution of the command which a previous call to AX=AE00h indicated was resident APPEND hooks this call BUG: Novell DOS 7.0's COMMAND.COM (prior to Update 12) will attempt to run a disk program with the indicated name even if the returned length byte is zero, because the register used to flag this case is clobbered without first checking it. The workaround is to set the command name buffer to "REM" followed by enough blanks to pad out the original command's length, which will also work with MS-DOS 6.
