Using Eu 2.4, you could do this:

constant dynInc = open("dyncommands.e","w")
--be sure to chooes some unique file name here
puts(dynInc,"include /blah/to/file/hello.e\n")
close(dynInc)
include dyncommands.e

The file holding a dynamic command list must be hardcoded, but you could 
generate its contents as needed.
This is reported not to work in 2.5, which is why I didn't switch to it, 
plus the added load time on my old secondary machine.
Search for "dynamic include" or "local include" in the archives. The 
solution I'm describing was exposed in details by I. Kachan iirc.

Are you sure you can modify env variables on the fly wothout some kind 
of logoff/logon pair?
And I'd add a \n at the end of any command string you pass to 
system[_exec], just in case.
