Test posting (on behalf of David Black)
Sun, 2007-01-28 19:20 — dabailey
I have ported a GWBasic program to QuickBasic V2 to take advantage of
speed through the compiler in QB2.
The compiler does not reflect any errors and the program runs, until it
hits a CHAIN command. Numerous sites touch on this, but I have not found
the answer so far. It seems to lie in the QuickBasic Manual which is also
hard to get hold of.
Not sure if anyone has a quick easy answer to this problem?.
Regards
Dave

When executing a program
When executing a program within the QB.EXE or QBX.EXE (QuickBasic Extended) environment that CALLs a Quick library routine that executes a RUN or CHAIN command, the system can hang under either of the following two specific conditions:
1.
If the program to be CHAINed or RUN does not exist in the current directory, the QuickBasic editor will hang.
2.
If the first program has been changed since being loaded, the QuickBasic environment will ask if you want to save the current program before loading the program named in the CHAIN or RUN statement. An "OK" or "No" response allows QuickBasic to load and execute the CHAIN or RUN program correctly. A "Cancel" response causes QuickBasic to drop to DOS. Attempting to rerun QuickBasic after the drop to DOS will hang the machine.

When executing a program
"Attempting to rerun QuickBasic after the drop to DOS will hang the machine." Maybe the old thread of QuickBasic is running even after a cancel and when you want to start QuickBasic again it will produce a deadlock and the machine hangs. Company Logo Design
