     I see no reasons for this (this not adds required/used functionality),
especially this will eat extra memory for additional parsing code and may
introduce incompatibilities into existing parser (which anyway is too complex).

     After all, DOS isn't POSIX system and DOS programs don't use/need extra
garbage in environment. This may be useful _only_ to ease porting sources of
unix programs to DOS, but there exist more elegant solutions (ie., for these
programs should be used library/startup, which will modify environment
statically or on the fly as need - similarly, as many compilers include
wildargs.obj, which emulate wild characters expansion by shell).

     Of course.

PS: Blair, when you answer about using string instructions in callint()?
