In answer to your second question, the simplest way I can think of doing this is to use something similar to the following:

procedure format
{M$ 2000,0, 0}
uses dos;
var forpar : text; {forpar steht for format parameter}
write (´Parameter:´);
readln (forpar);
exec (´A:\format.com´ , forpar)

The section in question I am really pointing out here is:

exec (´A:\format.com´ , forpar)

Hope this helps.
