IXI Visual Tcl
==============
Welcome to IXI Visual Tcl 1.0C1
DESCRIPTION
===========
IXI Visual Tcl is a high-level graphical scripting language for graphical
terminals. IXI Visual Tcl interprets commands and constructs graphical output
using Motif, allowing the production of sophisticated graphical applications
without the complexity of Motif.
IXI Visual Tcl is a multi-platform port of SCO Visual Tcl.
INSTALLATION
============
To install IXI Visual Tcl, do the following:
1. Choose a directory in which to install IXI Visual Tcl. The
recommended location is /opt, although you may choose a different
location if you wish. Move to this directory by typing:
cd /opt
2. Extract the software by typing one of the following:
Solaris: tar xvf cdromdir/IXIvt10s.tar
SunOS: tar xvf cdromdir/IXIvt10x.tar
replacing cdromdir with the name of your mount directory. See the
IXI Premier Motif Installation & Release notes for more information.
CONFIGURATION
=============
If you installed IXI Visual Tcl in the recommended location, IXI Premier Motif
configures all the appropriate environment variables automatically.
If you installed IXI Visual Tcl in a different location, you should do the
following to correctly configure your system, replacing tcl_dir with the
pathname of the directory in which you installed IXI Visual Tcl:
1. Add the bin directory to your PATH environment variable by typing one
of the following:
Bourne shell: PATH=tcl_dir/IXIvt10s/bin:$PATH ; export PATH
C shell: setenv PATH tcl_dir/IXIvt10s/bin:$PATH
2. Set the VTCL_HOME environment variable by typing one of the following:
Bourne shell: VTCL_HOME=tcl_dir/IXIvt10s/lib/vtcl ; export VTCL_HOME
C shell: setenv VTCL_HOME tcl_dir/IXIvt10s/lib/vtcl
3. The remaining environment variables needed by IXI Visual Tcl can now
be set automatically by typing one of the following:
Bourne shell: . $VTCL_HOME/sh-env
C shell: source $VTCL_HOME/csh-env
TESTING
=======
A number of test scripts are provided to test every aspect of IXI Visual Tcl.
These are located in $VTCL_HOME/tests. To run a test, do the following:
1. Move to the tests directory by typing the following:
cd $VTCL_HOME/tests
2. Run the test suite program by typing the following:
vtcl Browse.tcl
3. You are presented with a list of test scripts. To view a test script,
click on its name in the list. To run a script, click on the Execute...
button. To quit the test suite, click on the Close button.
DEMOS
=====
Demonstration programs are located in $VTCL_HOME/examples. To run a
demonstration program, do the following:
1. Move to the examples directory by typing the following:
cd $VTCL_HOME/examples
2. Run the appropriate program by typing
vtcl demo_name
replacing demo_name with the filename of the demonstration program you
wish to run.

Visual Tcl 1.0C1 RELEASE NOTES
==============================
1) SunOS 4.1.x and Solaris 2.x:
* There is no character based display engine. Please ignore
all references to CHARM, and/or character display server in
the documentation.
* There is no Help support available, except for Help ON_VERSION.
* The dialog box options -apply and -cancel are only available for
VtFormDialog and VtFileSelectionDialog.
* If for any reason Visual Tcl hangs, you may need to kill the daemon
server process and restart your application. This
also terminates all current vtcl applications connected to the
server. To kill the daemon server process, do the following:
1. To discover the process ID number of the daemon, type
one of the following:
Solaris: ps -elf | grep xm_vtcld
SunOS: ps -aux | grep xm_vtcld
2. Kill the process by typing the following:
kill -9 pid
replacing pid with the process ID returned by step 1.
2) SunOS 4.1.x only:
* SunOS limits the number of IXI Visual Tcl shells that can be
run concurrently to 5. To run more shells concurrently, you
must increase the value of FIFOCNT and rebuild the
kernel. You should install patch number 100347 before
attempting to do this.
* Problems may occur under SunOS if you do not exit your IXI
Visual Tcl shell cleanly. The VtClose command should always be used
to exit a shell. Do not attempt to exit a Visual Tcl
application by sending signals such as SIGKILL or SIGSTOP.
If for some reason you must terminate a script using a
process ID, do the following:
1. Identify the process by typing:
ps -aux | grep vtcl
2. Kill the process by typing:
kill pid
replacing pid with the process ID returned by step 1.
Note that you should not use `kill -9', as this may
hang the IXI Visual Tcl server.
