Versions 3.0 and 3.0b of Microsoft Mail for Windows permit calls to dynamic-link libraries (DLLs). Some calls to these DLL files require the parameter <PARAMBLK>. This parameter is case sensitive and must be in all uppercase letters.
The SHARED.INI file that is included with versions 3.0 and 3.0b of Microsoft Mail contains a sample line for the HelpRequest option in the [Custom Messages] section. Page 39 of the Microsoft Mail "Technical Reference" manual on shows an example of this line. This sample line may be confusing.
The sample HelpRequest line specifies an <ExtsDir>. The word "ExtsDir" generally is replaced with word `PARAMBLK`. This word must be in all uppercase letters. If you use any lowercase letters in the word "PARAMBLK," the function will fail.

Additional query words: 3.00 3.00b capital letters
