IXI Visual Tcl

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.

The License agreement for use of IXI Visual Tcl is available at the bottom of this page.

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 directly from the SCO Skunkware 5 CD-ROM by typing one of the following comands :
   • Solaris for SPARC:

     zcat /usr/skunk/tls/tls074c.solsparc.Z | tar xf -

   • SunOS for SPARC:

     zcat /usr/skunk/tls/tls074c.sunsparc.Z | tar xf -

   • SunOS for Intel:

     zcat /usr/skunk/tls/tls085.solintel.Z | tar xf -

   • OSF/1 for Alpha:

     zcat /usr/skunk/tls/tls086.decalpha.Z | tar xf -

   • SGI IRIX:

     zcat /usr/skunk/tls/tls087.sgiirix.Z | tar xf -

   • HP-UX:

     zcat /usr/skunk/tls/tls088.hpux.Z | tar xf -

   • IBM AIX:

     zcat /usr/skunk/tls/tls089.ibmaix.Z | tar xf -

   • GENERIC IXI VISUAL TCL DOC:

     zcat /usr/skunk/tls/tls090.ixidoc.Z | tar xf -

     replacing /usr/skunk with the name of your mount directory. This documentation is applicable to all ports of IXI Visual Tcl 1.0C1. Install to your preferred directory. To view these man pages, select the IXIVtcl/TOC.html page.

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
   

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.

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.

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.
