Description
Used only on the Macintosh to convert a four-character constant to a value that may be used by Dir, Kill, Shell, and AppActivate.
Syntax
MacID(constant)
The constant named argument consists of four-characters used to specify a resource type, file type, application signature, or Apple Event. For example, TEXT, OBIN, MSWD (Microsoft Word), XCEL (Microsoft Excel), and so on.
Remarks
MacID is used with Dir and Kill to specify a Macintosh file type. Since the Macintosh does not support '*' and '?' as wildcards, you can use a four-character constant instead to identify groups of files. For example, the following statement returns 'TEXT' type files from the current folder:
Dir("", MacID("TEXT"))
MacID is used with Shell and AppActivate to specify an application using the application's unique signature.

' Deletes all "TEXT" files in the current folder.
Kill MacID("TEXT")
' Run Microsoft Excel.
ReturnValue = Shell(MacID("XCEL"))
' Activate Microsoft Word.
AppActivate MacID("MSWD")
