Library /sys$common/syshlp/helplib.hlb — SET TERMINAL Qualifiers /ANSI_CRT
/ANSI_CRT (default)
/NOANSI_CRT
Controls whether the terminal conforms to ANSI CRT programming
standards. Because ANSI standards are a proper subset of the DEC_
CRT characteristics, the default for all VT100 family terminals
is /ANSI_CRT.
