If an attribute value includes blank spaces, the value must be enclosed in single quotes. For example:

:font facename='Tms Rmn'.

Notice that the value has initial capitals. For this particular case, they are required; otherwise, the IPF compiler will not recognize them as valid values.

Using some of the tags described thus far, you could produce a source file like this:

:userdoc.
:h1 res=001.Save the Manatee
:p.
There are fewer than 1200 manatees in the state of Florida.
Ten percent of the existing herds die each year
because of:
:sl compact.
:li.Contact with boat propellers
:li.Impact from boats and barges
:li.Entrapment in locks and dams.
:esl.
:euserdoc.

The output produced from the source file is an OS/2 standard window.

The menu-bar choices, Services, Options, and Help are provided automatically by IPF. The title-bar line, "Save the Manatee," is generated by the :h1. tag. The viewing area of the window displays the formatted information.

The best way to learn about tags is to study the examples provided in the following sections, then create some windows of your own.
