Is there a way that a program can do:

Found it right after posting, change "COMSPEC". Which works, but only
sort of.
I have a program "execinput" which takes input and for each line does
system();
Changed COMSPEC in a mintty window in bash shell to point to bash, then
did
set COMSPEC='C:\progs\msys32\usr\bin\bash.exe'
echo 'pwd' | execinput
(prints the current directory) #<-- in cmd.exe pwd throws an error,
so it is in bash
echo 'ls -al' | execinput
(lists as expected)
echo 'echo one' | execinput
one
#it goes wrong at the next command
echo 'echo one ; echo two ; echo three' | execinput
one ; echo two ; echo three
echo 'echo one & echo two & echo three' | execinput
one
two
three
So it seems to work for ONE command, but for a compound command
for whatever reason it expects cmd.exe style command separators and not
bash ones.
Is some other environmental variable required to make compound commands
work?
Thanks,
