[aplusdev] Re: Source code change to src/a/u.c to report DOS text APL script corruption

[John.Mizel at morganstanley.com]

Hi Art,

Thanks for the change, I'll add it to our code base.  I also have some
changes and new features pending.

I'm suprized 2.96 caused you problems.  Our next build will use some
release of 3.2, though we no longer have the hardware or resources to
create all the binaries we currently have available for 4.18-8.

Thanks,
John
