Component - ActionScript - Composition

A program (Action-Script) in the languge CG_AT has the following syntax.

• An Action-Script starts with a line containing the keyword ACTION_BEGIN to be started in column 1.

• An Action-Script ends with a line containing the keyword ACTION_END to be started in column 1.

• Between the first and the last lines the commands (Actions) occur.

• A line starting with a ‘!’-character is a comment-line.

In the next table the different groups of actions are presented.

Actiom groups	Description
&*File*&s actions	Bestandsnamen en output-bestand.
&*Param*&eter actions	Setup parameters-environment
&*Datadic*&tionary actions	Setup datadictionary environment.
&*Context*& actions	Setup Context- environment.
&*Struct*&uring actions	Ifs and Loops.
&*Subst*&itution actions	Actual generation.
&*Format*& actions.	Layouting the output-file.
&*String*& actions.	String manipulation.

In general an Action-Script contains the following sequencesoif Actions

• In most Action-Scripts a number of files are defined (FILNAM actions).

• Subsequently the environments are set up (Datadictionary-actions, Parameter-actions, Context-actions).

• Within the environments the actual substitutions are executed by indicating which Template-pieces have to be processed, i.e. substituted while the result is written to the output-file (Substitution-actions).

• To format the output, layout-actions can be used (Format actions).

• For the processing of the text-files a number of extra actions are available, enabling the defenition of Finite State Machines (String actions).

Within Action Scripts subroutines can be used.

• The main program must contain CALL actions to call the subroutines.

• The main program must be ended by a STOP- and END-statement.

• After the STOP- and END-statement de different subroutines are placed.

• Subroutines start with a SUBROUTINE statement.

• Subroutines end with a RETURN- and END-statement.

See also Subroutine-actions.

Component - ActionScript - Actions.

With the menu-option Generating - Actions the Actions-list can be maintained: The Action-Script, that should be executed must be the first block of the file and it must be followed by an empty line.

With the menu-option Generating – Generation the Generation-process is started with the first Action-Script that is found in the Actions-list.

Actions.

An action consists of maximally 4 words.
The first word is the command-woord and indicates which action has to be executed.
Most actions may contain one or more parameters.
These parameters are substituted before the action is executed.

If you like the header, it can be found here.

Images

If you are using firefox, put your cursor over the logo. But for some reason IE does not like image rollover effects. Its not that big of a deal.
