environment variable (to the same value as SBBSNNUM) as some door games
(e.g. Bordello, by T&J Software) have support for this environment variable
built into their configuration file parsing. This makes setting up multiple
nodes much easier/faster, as you can re-use the same configuration file for
all of them by just specifying this environment variable in the .cfg file
(e.g. "c:\sbbs\node%PCBNODE%\door.sys"). Unfortunately, you can't use just
*any* environment variable, it has to be one of the ones specifically supported
by their programs (or door frame door kit?). Anyway, this simple hack can save
a lot of time setting up some of these doors.
I did not do this for executing native (32-bit) programs as I'm pretty sure
there was never a 32-bit version of PCBoard, so that wouldn't make much sense.
