This is the sample contacts management system written in RAD. Use the DOS XCOPY command to copy program files to your local hard drive. Assuming that the local hard drive is C: the systax would be: XCOPY . C:\CONTACTS /E/I/H To launch the program from dos type: angossx -radc:\contacts >From windows create a program item or task. The command line would be: ANGOSSW.EXE -radc:\contacts It is assumed that your ANGOSS system is installed in C:\ANGOSS if this is not the case you may need to make sure that the directory with your ANGOSS system files is in your path statement. If you want to put the contacts manager in another directory you can change the pathing information using PATHSET see the Developer Manual. The source code for the calendar function is in the High Use Application Library, check out the calculations on the date fields to see how it is called.
