Compatibility: 4.0+

Purpose: Loads and executes a TSR  (before starting AUTOEXEC.BAT).

Uses:   Avoid some memory loss due to DOS environment duplication.

  Hide installation of system-level programs such as Share and

Nlsfunc in the "permanent" CONFIG.SYS file, rather than loading

them in the often-edited AUTOEXEC.BAT file.

  Give your favorite TSR a chance at intercepting interrupt

vectors before COMMAND.COM is loaded.

Syntax: INSTALL=[d:][path]filename.ext [progParms]

  Parameters  

d:\path\filename.ext is the drive, path, filename and extension of the

program to be installed.  Only certain DOS external commands and

third-party TSR  programs can be installed this way.

progParms specifies command-line parameters (filenames, switches, etc.) for

the program being installed.

  TECH Notes  

  On DOS versions prior to DOS 6.0, a TSR loaded via INSTALL= does not

have access to a valid DOS Environment block.  DOS 6.0+ does provide a

copy of the DOS environment and does follow the standards described in

Program Startup & Exit.

HOWEVER, the environment block does NOT remain in memory after

installation.  TSRs should access it only when starting up.

  Your TSR may wish to allocate upper memory when it is available (see

Accessing Upper Memory for info).  However, you should always provide a

command-line switch to force it to use only conventional  memory (or

you'll irritate folks who are saving their UMBs for special purposes.
