- 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.
-
- Examples
-
- To start CopyQM in 7-bit display mode and copy using drive A::
-
- COPYQM A: 7BIT
-
- To view the diskette configuration:
