/NOPACKC[[ODE]]
This option turns off code-segment packing. Code-segment packing is on by default for segmented executable files and for DOS programs created with overlays or with the /TINY option. It is off by default for other DOS programs. If an environment variable (such as LINK or CL) includes the /PACKC option to turn on code-segment packing, you can use /NOPACKC to override /PACKC. For more information on packing, see “The /PACKC Option”.
NOTE:
The minimum unique abbreviation for /NOPACKC has changed from /NOP to /NOPACKC.
