<H2>BUGS</H2><PRE>
If you call <STRONG>tgetstr</STRONG> to fetch <STRONG>ca</STRONG> or any other parameterized
- string, be aware that it will be returned in terminfo
- notation, not the older and not-quite-compatible termcap
- notation. This won't cause problems if all you do with it
- is call <STRONG>tgoto</STRONG> or <STRONG>tparm</STRONG>, which both expand terminfo-style
- strings as terminfo. (The <STRONG>tgoto</STRONG> function, if configured
- to support termcap, will check if the string is indeed
- terminfo-style by looking for "%p" parameters or "$<..>"
- delays, and invoke a termcap-style parser if the string
- does not appear to be terminfo).

Because terminfo conventions for representing padding in
string capabilities differ from termcap's, <STRONG>tputs("50");</STRONG>
will put out a literal "50" rather than busy-waiting for
50 milliseconds. Cope with it.
+ Note that termcap has nothing analogous to terminfo's <STRONG>sgr</STRONG>
+ string. One consequence of this is that termcap applica-
+ tions assume me (terminfo <STRONG>sgr0</STRONG>) does not reset the alter-
+ nate character set. This implementation checks for, and
+ modifies the data shown to the termcap interface to accom-
+ modate termcap's limitation in this respect.
