• Schedule

Module 1 Overview of TACL Features

• TACL as a command interpreter
• Productivity tools and information aids

Module 2 TACL VariablesT

• Obtaining information about variables using either commands or built-ins
• Using commands or built-in functions to create, initialize, modify, and eliminate variables
• The use of “frames” and variable management
• Lab exercise (30 minutes): Learn and understand how to logon and use defined function keys
• Practice using TACL interactively

Module 3 Editing Variables

• Performing variable file I/O
• Performing global editing of a variable
• Performing line editing of a variable
• Performing character editing of a variable
• Locating the position of a string within a variable
• Extracting lines and characters from a variable
• Lab exercise (1 hour): Exercising variable editing

Module 4 Writing Functions: Macros

• Macro functionality and syntax
• Parameter substitution
• Writing macros
• Using nested macros
• Lab exercise (30 minutes): Write a simple TACL macro

Module 5 Writing Functions: #IF

• Write functions that use the TACL #IF |THEN| |ELSE| construct
• Making string comparisons
• Using #IF NOT
• Lab exercise (1 hour): Write a macro that accepts one or more arguments and uses #IF

Module 6 Writing Functions: #LOOP

• Using the #LOOP |DO| |UNTIL| construct
• Using the #LOOP |WHILE||DO| construct
• Lab exercise (1 hour):Write a macro that uses a #LOOP construct

Module 7 Writing Functions: #CASE

Syntax and use of the #CASE construct

Module 7 Writing Functions: #CASE

• Using the TACL debugging facility to aid in getting functions to work properly
• Lab exercise (2 hours): Start and stop the debugger
• Set and clear breakpoints
• Display and modify the contents of a variable
• Single step through functions and resume execution
• Write a function that makes use of the #CASE built-in

Module 9 Writing Functions: Routines

• Writing “Routine” type functions; using #ARGUMENT, #MORE AND #REST
• Describe the additional capabilities that routines offer that macros do not
• Describe the use of the built-ins: #MYSYSTEM #PROCESSORSTATUS, and #PROCESSORTYPE
• Lab exercise (2 hours): Modify TACL programs to use routine type functions

Module 10 INLINE Processing

• Performing process I/O using the INLINE facility
• Controlling the display of process output
• Describe the use of #INLINEPREFIX, INLPREFIX, #INLINETO, and INLTO
• Lab exercise (1 hour): Use the INLINE facility to interface with the PERUSE utility

Onsite-Delivery Equipment Requirements

• NonStop operating system D30 or later for NonStop K-series servers, or any Gxx version for NonStop S-series servers
• Pathway/TS (version D30 or later), NonStop TMF
