I keep getting the "SYSTEM RESOURCE MISSING" message when I type APP95 at the DOS prompt on my PC.

You have installed the Connectivity pack on a drive other than C: or a directory other than CPACK. This is okay if the APP95 program can find where you've put the Connectivity Pack modules. To find the modules, APP95 looks to the DOS environment for a variable named PIMS, which should be set with the path to the Connectivity modules. The command to define this variable is set pims=c:\cpack (you should replace C:\CPACK with your own path).

To display the current values of the DOS environment file, type set at the DOS prompt. PATH and PIMS should both contain the path to the Connectivity modules.

The SET PIMS command should be in the AUTOEXEC.BAT file. The problem may be that the SET PIMS command is not executed during the start-up process because it is preceded by the execution of another program. To fix this, put the SET PIMS command nearer the beginning of the AUTOEXEC.BAT file. After this is changed, save the AUTOEXEC.BAT file and reboot the PC. After rebooting, type app95 and press <ENTER>.
