If you are working under WIN98 (other WIN version may also work) you
can use the environment variable CMDLINE:

example:

uses dos;
begin
  writeln('Command line: ', GetEnv('CMDLINE'));
end.

In the following screen output, cl is called from a bat file:

C:\TMP>cl
1234567890123456789012345678901234567890123456789012345678901234567890

12345678912345678900
Command line:cl 123456789012345678901234567890123456789012345678901234

As you see then full 255 Bytes of a string are used, if you write a
pChar-GetEnv you should get the whole command line.

You should do some processing, because for example WIN file name from
the explorer can contain spaces and may be enclosed in ".

Borland newsgroups dislike crossposting - see sig below.

Borland newsgroups have their own proper server - see sig below - the
Borland experts will not see your post; nor this one.

This seems off-topic for at least one of c.l.p.borland & c.l.p.misc; did
you not read the regular informative posts?


AIUI, the parameter list is transferred in the upper half of the
256-byte PSP, at least for 16-bit programs such as TP/BP generate.  Not,
of course, that you have actually said which Pascal you are trying.

I would code such that if a parameter starts with '@', the rest of it is
the name of a file from which further parameters are now read.
