Supplemental Information for DBCS System Users

Overview

Commencing with version 3.12, allowances for certain aspects of dis-
plays using double-byte character (DBCS) encoding have been incor-
porated into the CopyQM product set. Certain ideographic writing sys-
tems, such as Chinese and Japanese Kanji make selective use of two-
byte character sequences to represent certain symbols. This causes
display problems when a program attempts to use the PC extended charac-
ter set for line drawing and other purposes.

Description of Changes

All of the CopyQM product set has been modified to check for the
presence of the E-Ten Chinese System display software. In addition,
all CopyQM products accept a command-line switch of either /7BIT or
7BIT which will manually force use of alternate character sets and dis-
play color schemes that do not conflict with the requirements of a
DBCS-aware system.

In most cases, displays are altered to supplant line-drawing graphic
characters with contrasting color schemes. In the case of a
monochrome display, where color cannot be used for contrast, line-
drawing characters have been replaced with the asterisk "*", usually
as a border character in boxed text.

In all cases, when DBCS operation is specified, no character with a
value above decimal 127 will be used in displays by CopyQM. However,
8-bit text which is entered by the user will be displayed without
modification.

If the /7BIT switch is used as a command-line option for CQMENU, it is
passed to CopyQM, as is the /MONO (monochrome display) switch.

Users of the Taiwanese E-Ten display system should not have to ex-
plicitly specify 7BIT, as detection of the E-Ten software is automati-
cally performed by all products. However, if the E-Ten system is
placed in the non-DBCS mode, CopyQM will execute in full 8-bit PC
mode, even if the E-Ten display mode is changed during the session.
