NOTES TO TCU 3.2 DELIVERY
============================================================================
Naming Convention
-----------------
In order to provide a safer naming convention, all services now
have the prefix 'tcu_'. For example, 'load_form' is now called
'tcu_load_form'. Furthermore, all upper-case constants and types
defined in TCU.H are prefixed with 'TCU_', e.g. TCU_MENU. By
defining the symbol '__TCUPRE32__' the old naming conventions may
still be used though this will be discontinued at some future stage.
All new code should use the 'tcu_' & 'TCU_' prefixes, and existing
code should, in time, be modified to conform to the new names. The
definition of the symbol __TCUPRE32__ may be done either in the
integrated environment, with the command line compiler option
-D__TCUPRE32__ or by explicitly defining it in the code as:
#define __TCUPRE32__
#include <usr\tcu.h>
Note that the new services added with version 3.2 have no old
style naming convention. 'tcu_write_formrec' may not be specified
as 'write_formrec'.
Installation Program
--------------------
Version 3.2 comes complete with an installation procedure to make
installation of the system simpler. The installation does nothing
other than to copy files and merge libraries if requested. There
are no nasty surprises! The installation program source code is
supplied as an additional demonstration.
In order to install the system, unpack the COMPLETE distribution
file, TCU_32.ZIP, into a temporary directory, move into this
directory and type 'tcuinst'. After installation the complete
directory may be deleted as any files required will have been
copied to the final destinations. An example installation session
is shown below:
C:\> md tcu_tmp
C:\> cd tcu_tmp
C:\TCU_TMP> pkunzip a:tcu_32
: : :
: : :
C:\TCU_TMP> tcuinst
C:\TCU_TMP> del *.*
Are you sure? y
C:\TCU_TMP> cd ..
C:\> rd tcu_tmp
C:\>
The system will now have been installed (provided you completed the
procedure within TCUINST).
Please be sure to read AA-READ.ME! and TCU.DOC for full information
on changes since the last version and a reference guide to this
version.
