The program allows you to select:

In order to run Free Pascal from any directory on your system, you must extend your path variable to contain the C:\PP\BIN directory. Usually this is done in the AUTOEXEC.BAT file. It should look something like this :

  SET PATH=%PATH%;C:\PP\2.2\BIN\i386-DOS

for dos or

  SET PATH=%PATH%;C:\PP\2.2\BIN\i386-OS2

for os/2. (Again, assuming that you installed in the default location).

On os/2, Free Pascal installs some libraries from the EMX package if they were not yet installed. (The installer will notify you if they should be installed). They are located in the

C:\PP\DLL

directory. The name of this directory should be added to the LIBPATH directive in the config.sys file:

LIBPATH=XXX;C:\PP\DLL

Obviously, any existing directories in the LIBPATH directive (indicated by XXX in the above example) should be preserved.

Optional Installation: The coprocessor emulation

For people who have an older CPU type, without math coprocessor (i387) it is necessary to install a coprocessor emulation, since Free Pascal uses the coprocessor to do all floating point operations.

The installation of the coprocessor emulation is handled by the installation program (INSTALL.EXE) under dos and Windows.
