The LANSA template language is a simple “tag” language that relies on branch type logic. It is not a sophisticated programming language. All commands conform to the normal LANSA command conventions. For instance, positional or keyword parameter specification can be used, lists must be enclosed in brackets, etc. The template language is not compiled. It is an interpretive language.
Note: In the lists below, ‘*’ indicates user input requested.
