I have observed these problems with DeltaCad. Regards, Steve


1) If your PC graphics mode is 1280x1024 or greater, the functions for text
editing misbehave. Multiple spurious error messages are generated which the
user has to click on before processing can continue. This is the worst
problem I know of, as I encounter it frequently. Once past the spurious
errors, the text edit box can be used and processing normally continues.

2) However, if the chosen action is to alter the justification of the text,
the application loops and then crashes.

3) Splines must not have more than 248 points, and irregular polygons
(shapes) are limited to 748 points. If more points are used, either or both
of the application menu and the drawing will be corrupted. There is no error
message on the call to dcCreateSpline and no warning in the manual that
these limits exist. I only found out about it after sending their tech.
support a failing programme. I was making splines with 365 points when I hit
the problem. The limit is a trap for the unwary, but since drawings are not
noticably degraded by omitting every second day, it is simply a matter of
using only 183 points in a curve. I moved over to using splines because the
drawing is generated much faster than when multiple straight line elements
are used.

4) The Basic interpreter intermittently reports spurious syntax errors if
there are a series of subroutine calls one after another, where the
subroutine takes more than one parameter and the parameters values supplied
are constants e.g.

  ...
  do_sub(1,2)
  do_sub(3,4)    'an error is reported for this line.
  do_sub(5,6)
  ...

  Sub do_sub(ByVal param1, ByVal param2)
  ...
  End Sub

It seems to go away if you use the Call keyword:

  Call do_sub(1,2)
  Call do_sub(3,4)
  Call do_sub(5,6)
....
