The READ statement cannot read DATA statements that are in another
module. READ statements are allowed within subprograms, but will only
read DATA statements that are in the same module that the subprogram
is in. DATA statements themselves cannot be included inside SUB or
FUNCTION procedure definitions; they must be located at the module
level code of each module.

This information applies to Microsoft QuickBASIC Versions 4.00, 4.00b,
and 4.50 for MS-DOS, to Microsoft BASIC Compiler Versions 6.00 and
6.00b for MS-DOS and MS OS/2, and to Microsoft BASIC Professional
Development System (PDS) Version 7.00 for MS-DOS and MS OS/2.

If a READ statement is executed and there are no DATA statements in
that module, an "Out of data" error is generated. The READ statement
does not look for DATA statements in other modules. This limitation of
the READ statement is not explicitly stated in any documentation. This
information needs to be added to the READ and DATA statements (listed
alphabetically) in the following manuals:

1. "Microsoft QuickBASIC 4.5: BASIC Language Reference" for Version
   4.50

2. "Microsoft QuickBASIC 4.0: BASIC Language Reference" manual for
   Versions 4.00 and 4.00b

3. "Microsoft QuickBASIC Compiler" Versions 2.0x and 3.00 manual

4. "Microsoft BASIC Version 7.0: Language Reference" manual

5. "Microsoft BASIC Compiler 6.0: BASIC Language Reference" for
   Versions 6.00 and 6.00b
