/*
* This file contains the machine dependent escape sequences that
* the editor needs to perform various operations. Some of the sequences
* here are optional. Anything not available should be indicated by
* a null string. In the case of insert/delete line sequences, the
* editor checks the capability and works around the deficiency, if
* necessary.
*
* Currently, insert/delete line sequences are used for screen scrolling.
* There are lots of terminals that have 'index' and 'reverse index'
* capabilities, but no line insert/delete. For this reason, the editor
* routines s_ins() and s_del() should be modified to use 'index'
* sequences when the line to be inserted or deleted line zero.

#ifdef OS2
/*
* The OS/2 ansi console driver is pretty deficient. No insert or delete line
* sequences. The erase line sequence only erases from the cursor to the end
* of the line. For our purposes that works out okay, since the only time
* T_EL is used is when the cursor is in column 0.
