Versions 2.20, 2.30, 2.35, and 3.10 of the Microsoft CodeView debugger
do not support the BASIC CHAIN command. When a program is CHAINed in
BASIC, CodeView executes the entire CHAINed-to program and will not
allow it to be single-stepped through.

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) versions 7.00 and 7.10 for MS-DOS and MS
OS/2.

The CHAIN command is unique to BASIC and is not supported by the
CodeView debugger. CodeView is a mixed-language source code debugger
supplied with BASIC compiler versions 6.00 and 6.00b and BASIC PDS
versions 7.00 and 7.10. CodeView is NOT shipped with QuickBASIC 4.00,
4.00b, or 4.50 for MS-DOS.

The following table lists which versions of CodeView are shipped with
which versions of BASIC:

   BASIC Version      Is Shipped with CodeView Version
   -------------      --------------------------------

   6.00               2.20
   6.00b              2.30
   7.00               2.35
   7.10               3.10

Note: CV.EXE is the CodeView utility for MS-DOS. CVP.EXE is the
CodeView utility for MS OS/2.
