Macintosh QuickBASIC May Load Wrong or Unexpected File (35719)
This article was previously published under Q35719
SUMMARY
In a certain situation, QuickBASIC may open an unexpected file.
If you sublaunch a compiled program with the "Launch After Compiling"
option in QuickBASIC and the compiled program crashes with a system
error or you restart the machine before the program quits, QuickBASIC
will load the source file of the interrupted compiled program the next
time you run QuickBASIC. The crashed program's source is loaded even
if you double-click a different source file, or you just start
QuickBASIC from the Finder. This process is surprising but harmless.
Before a compiled application is sublaunched, a file called
"QuickBASIC Resume" is created in the System folder to remember which
source file QuickBASIC was working with. When QuickBASIC is started
(whether returning from a sublaunch or being launched from the
finder), it looks for the "QuickBASIC Resume" file in the system
folder. If the file is there, QuickBASIC opens the specified source
file and deletes the "QuickBASIC Resume" file. If QuickBASIC can't
find the "QuickBASIC Resume" file, it looks to see if a file was
double-clicked in the Finder.
MORE INFORMATION
If the source file of the sublaunched, compiled, and crashed program
was saved in Text format, it will load the next time you run either
Microsoft QuickBASIC (b) or (d). Each version of QuickBASIC can read
only it's own compressed format (binary or decimal). Thus, if you
start the other version of QuickBASIC after the crash of a sublaunched
program, and the file was saved as compressed, the file will not be
loaded.
The "QuickBASIC Resume" file is created only when automatically
sublaunching a newly compiled application. It is not created when you
use the Sublaunch library routine in a program or the command window.
