USAPI.DLL

If USoft Developer is installed, USAPI.DLL and the example files for creating your own DLL to access USAPI.DLL will also be installed. The USAPI header and library files needed to create your own DLL are installed in the INCLUDE and LIB subdirectories of the installation directory.

If USoft Production is installed, then only USAPI.DLL will be installed, in the BIN subdirectory of the installation directory. This directory must be added to the PATH command in your AUTOEXEC.BAT file.
