To reserve a file in a CMS
library
CMS generation (optional)
Leave this field blank unless you want to reserve an earlier generation
or a variant generation rather than the latest main-line version.
Retrieve a local copy of the file(s) from CMS?
By default, the file in the CMS library replaces any local copy of the file
in the NetBeans Explorer. You should unselect this check box only if you
want to use the file already on your local filesystem rather than the one
in the CMS library.
Prompt for Input on Each Successive File
Select this option if you want to add different remarks or select different
options when checking out multiple files.

Note When you select a form node
, you are actually reserving two files in the source control library: the .form file and a corresponding .java file.
In the Explorer, the file status is updated to show a [Reserved; <n>] status (where <n> is the generation number of the file).
