Alsys Ada Compiler DOS/DOSE Packages

[debs.wisbey@amsjv.com (Debs Wisbey)]

Dear All,

I currently have a software program that is written in Ada and built
using the Alsys Ada 286/DOS compiler v4.3 and I am trying to port it
to the GNAT 3.10p Ada compiler for MS-DOS.  Unfortunately, my current
software contains numerous calls to the DOS and DOSE packages that, I
think, are specific to the Alsys Ada compiler.

Does anyone know where I can find equivalent functions/procedures or a
more detailed explanation of the package contents (other than the
specs) so that I can create some packages that in effect do similar
things?

Also, does anyone know if you can draw a table/grid and then populate
it with values?  This entails positioning the cursor on the screen at
a given co-ordinate and as of yet I cannot find a way of doing it.  My
only solution is to redraw the screen each time values change, which
is not very efficient.

Thank you for any help that you can give me,
Debs.
