SYMPTOMS
A &quot;Type Mismatch&quot; error does not occur if the INPUT statement receives any of the following noninteger-type symbols in an integer variable:


 * 1) d (double-precision exponential)
 * 2) e (exponential)
 * 3) ! (single-precision exponential)
 * 4) # (double-precision exponential)

Instead, a value of 0 (zero) is input. QuickBasic automatically converts the noninteger-type symbol to zero (0) instead of giving a &quot;Type Mismatch&quot; error message.



STATUS
Microsoft has confirmed this to be a bug in QuickBasic versions 3.00, 4.00, 4.00b, and 4.50 for MS-DOS; in Microsoft Basic Compiler versions 6.00, 6.00b for MS-DOS and MS OS/2; in Microsoft Basic Professional Development System versions 7.00 and 7.10 for MS-DOS and OS/2; and in Microsoft GW-Basic Interpreter versions 3.20, 3.22, and 3.23 for MS-DOS. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

NOTE: The &quot;Type Mismatch&quot; error message occurs in the above products, except for Basic PDS 7.00 and 7.10, if you input only a percent sign (&quot;%&quot;, which marks integer constants) in response to INPUT for an integer variable. In Basic PDS 7.00 and 7.10, a % is correctly input with a value of zero.

The following code demonstrates the above problem: ' A value of zero is input if the following noninteger-type ' characters are input into an integer variable: d (double exponential), ' e (single precision exponential), !, and # INPUT &quot;ENTER AN INTEGER &quot;,i% PRINT i% END
