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

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 ".
