trisb:=$FC;
trisc:=$FF;
trisa:=$FF;
ADCON1:=$8E;
portb:=0;
while (true) do
begin
L1:
i:=0;
portb:=0;delay_ms(5000);
l:=adc_read(0);delay_ms(10);
while ((l<512)and (portc.0=0)) do
begin
portb.0:=1;
l:=adc_read(0);delay_ms(100);
i:=i+1;
if i=50 then goto L1;
end;
portb:=0;
while ((l>512)and (portc.1=0)) do
begin
portb.1:=1;
l:=adc_read(0);delay_ms(100);
end;
end;
end.

You're not reporting properly. You're showing compile-time errors (you need to mention that). What is "1 304"? Is that column/line numbers? You don't show the code lines with the errors. You need to show them and add comments where the errors are.

Now, your problem is non-ASCII characters in identifiers which are not valid Pascal identifiers. Again, it indicates that you didn't show relevant code: in the sample you show there are not such identifiers.

Do the following:

Makes sure you use ASCII characters only. First, make sure when you edit file, you safe in ANSI, not in any of the Unicode UTFs. The file should be without any Unicode BOM marker and uses ANSI encoding. For example, in Notepad's "Save As" there are four encodings, one of them is ANSI.

Further, make sure you do not use anything except valid characters in identifiers. The valid characters are A to Z or a to z. For this purpose, I would suggest you program only in English, even comments. Even you're more comfortable with a difference culture and you language allows non-English characters, writing programs in English only saves you from many troubles in future. In particular, it improves your chances to get a solution at CodeProject. :-)

Good luck,
