The \fB@RESET@\fP program writes strings including

the recommended 1K for the termcap entry; others do not.

Each termcap entry has two important sizes associated with it: before

-"tc" is the capability that

In summary, a termcap entry that is longer than 1023 bytes can cause,
on various combinations of termcap libraries and applications, a core
dump, warnings, or incorrect operation.
