> the following little program doesn't run under gpc version 2.0(18.104.22.168)!
This version of GPC is over two years old. Better upgrade to
at least gpc-19990118. (See `http://home.pages.de/~GNU-Pascal/'
for more information, or download the stuff from
> text = File of char;
This overrides the built-in `Text' type which has `readln' ...
> filearray = array[1..n] of real;
This cannot work since `read' from a `file of char' expects a
`char' variable to hold the value. You could however `read' a
`real' number from a `text' file (with the built-in `text').

That's probably due to an error in the obsolete gpc-2.0.
> I know that the program runs under a Sun-Compiler!
That's strange. Is `file of char' equivalent to `text' in the
Sun Compiler? According to the standard, it is not.
> when I substitute filearray = array[1..n] of real; by

Then both gpc-2.0 and your Sun's Pascal have the same bug
accepting a non-`char' variable as an argument to `read' from a
`file of char'. gpc-19990118 correctly rejects the program also
with `integer' unless you remove the `text = file of char'
Hope this helps,
