Library /sys$common/syshlp/edthelp.hlb CLEAR  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 The CLEAR (abbreviated CL) command deletes a buffer.

 Format: CLEAR buffer

 The buffer no longer appears on the list printed by SHOW BUFFER.  If the
 buffer was a macro, it is no longer a macro.  If the buffer contained any
 text, that text is deleted.  If that buffer was the current buffer, the
 current buffer becomes MAIN.  There are two exceptions to these rules: the
 buffers PASTE and MAIN.  The CLEAR command does not delete these buffers but
 just deletes their text.  Note that the argument is a buffer name, not a range
 specification:  CLEAR PASTE is valid, while CLEAR =PASTE and CLEAR BUFFER
 PASTE are not.
