It turned out that I was actually using bash 1.14.7. I upgraded to bash
2.03 and retested. The above commands work correctly in interactive mode
under bash 2.03, unlike under bash 1.14.7. However, compound commands
don't seem to work correctly in scripts. If I run the attached script,
testcomp.sh, I get the following output:

    bash-2.03$ ./testcomp.sh
    + bob
    ./testcomp.sh: bob: command not found
    + echo 127
    127
    + echo 0
    0
    + set +x

This happens with $SHELL set to C:\WINDOWS\COMMAND.COM or
c:\djgpp\bin\bash.exe.

Bye,
