This JPEG image is another screen shot of the TLIB Add-In for
Visual Basic 4.0.  This screen shot shows the Update/Check-In
options screen.  There are six option check-boxes shown on the
right, and a list of components on the left.  The six option
check-boxes are:

"D" - Discard Lock: [don't store]
"F" - Fast/Freshen
"K" - Keep Checked Out
"M" - Increment Minor Version
"S" - Specify Version
"B" - Store as new Branch

In this screen shot, the last option is highlighted, "B - Store
as new Branch."  At the bottom of the options screen is the pop-up
help-bar for this option.  It reads:

Branch: check to force TLIB to store the new version with a new 'branch' version number.

There are also buttons for "Help," "OK," and "Cancel"
