Terminal display attributes

The terminal display attributes and the alternate character set defined in curses(3ocurses) are supported in FMLI. If the terminal your application is being run on does not have these capabilities then they are approximated as best as possible by curses. If the terminal is capable of outputting graphic characters, inverse video, bold/dim, and so on, then these attributes will be available in FMLI, in the following places:

• in text frame definition files, in text defined in the text and header descriptors

• in form definition files, in the value assigned to the field-level descriptor name

• in the initialization file, in the value assigned to the banner descriptor

• in arguments to the message built-in utility

• in the argument to the indicator built-in utility

The character sequence to turn a terminal attribute on in FMLI applications is of the form \+xx. To turn the attribute off, the form \-xx is used. If xx is not a valid FMLI character sequence for a terminal attribute, the entire character sequence, as coded, is output.

``Table of FMLI character sequences for display attributes'' lists the FMLI character sequence names and maps them to the applicable curses defined constant.
