Below is the complete GETANS.TXT file found in the GOODIES\FNDATION subdirectory.
NOTE: This file answers eight questions asked in the GETLESS.TXT file about the EX1.APP application and how it implements a foundation READ. Both the EX1.APP and GETLESS.TXT files are located in the GOODIES\FNDATION subdirectory.
Answers to READ/Window/Menu Quiz
1. You would add one READ level each time you selected an application from
the menu and, therefore, would get 'Too many READs in effect." in short order.
2. Because the procedure 'menuhit' is contained within EX1.MPR which is not
part of EX1.PRG.
3. It's found in function 'stopread' which is evaluated each time an
application window is DEACTIVATEd.
4. There are at most three READs active: the foundation READ, one of the
application READs, and a READ MODAL associated with either 'browser' or 'finder'.
5. The procedure named 'efface', which is called in the cleanup code for
each application screen, ensures that when the last application window is closed the control panel is released.
6. The application READ has been terminated because its DEACTIVATE clause
has returned .T. but the foundation READ remains active.
7. The foundation READ is still active. 8. The first application's DEACTIVATE clause returns .T. and, thereby,
terminates that application READ. Termination of the application READ triggers the foundation READ's VALID clause. This routine, called 'myhandler', notes that WONTOP() is a new application READ then proceeds to execute the .SPR associated with that window.
