Termcap had grown very | large and on sub-1-MIP computers took a noticable delay to read on | every startup of programs using it. So, it was reordered to reduce | the startup time on common terminals. As Erik points out this | optimization | is no longer necessary as termcap is now placed in a database. Not to | mention that there are far fewer entries in it today than there were | at the peak of its existence. Actually, the current file in the repository is 10% longer (4667 lines vs 4007) than the first check-in. Where might I find a larger example (of BSD termcap) such as you are referring to? -- Thomas E. Dickey <dickey@invisible-island.net> http://invisible-island.net ftp://invisible-island.net
