SUMMARY

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.

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.
