SYMPTOMS

When two programs, both compiled with BC /O/X, CHAIN or RUN between one another, a "Hit any key to continue" error message is displayed if the CHAIN or RUN occurs in an error-handler routine. This problem does not occur if the programs are compiled to use the Basic run-time module (without /O).

STATUS

Microsoft has confirmed this to be a bug in Microsoft QuickBasic Versions 4.00b and 4.50 (buglist4.00b, buglist4.50), and Microsoft Basic Compiler Versions 6.00 and 6.00b (buglist6.00 buglist6.00b) for MS-DOS and OS/2. This problem was corrected in Microsoft Basic PDS Version 7.00 (fixlist7.00).

To work around this problem, use RESUME <label> to return program control to a label that contains the CHAIN statement.

MORE INFORMATION

The following is a code example:

'==== Prog a ====
ON ERROR GOTO trap
ERROR 57
END
trap:
   PRINT "error in a"
   'uncomment the next line to get the programs to work
   'RESUME leave
leave:
 CHAIN "b"
 stop

'==== Prog b ====
ON ERROR GOTO trap
ERROR 57
END
trap:
   PRINT "error in b"
   'uncomment the next line to get the programs to work
   'RESUME leave
leave:
   CHAIN "a"
   stop
