In the second SELECT CASE example available through QuickBASIC Version
4.50 Advisor on-line Help, there is an error in a CASE statement.

The following correction applies to "HELP: SELECT Statement
Programming Examples." To check for digit entry, the CASE statement
should read as follows

   CASE 48 TO 57

instead of the following:

   CASE 30 TO 29

The correct ASCII decimal values for digit entries 0 through 9 are 48
to 57.

Version 4.50 is the first version of QuickBASIC that offers the QB
Advisor, a hypertext-based, on-line help system with instant cross
referencing. This error was corrected in the QBX.EXE Microsoft Advisor
that is included with Microsoft BASIC PDS Version 7.00.
