LABEL
The LABEL .label command associates the specified label classification with the current record in Edit/Browse. The label is entered on the command line in the form:

You can also assign a label just by typing the .label part in the command line:

The first character of a label must be a letter in the range A-Y. Labels starting with Z are reserved.
The LABEL command associates the specified label classification with the top record displayed in the CHAR and VFMT mode of Edit/Browse.
You can also assign a label by scrolling to the desired record and entering the .label when in CHAR or VFMT mode and with the line number column displayed.
