| FLAGS |
Sets flags declared in LOCALFLAGS.
|
| SOUND |
Specifies sound effect to be looped (as it was background music).
|
| MUSIC |
Specifies background music.
|
| ENDLOCATION |
Tells the parser there is nothing more to read in this location script.
|
Level-0 block statements (with brief description):
| ZONE |
Declares interactive screen area.
|
| ANIMATION |
Declares visible animation.
|
| COMMENT |

|
| NODES |
Defines points to be used as aid when computing walk paths.
|
| COMMANDS |
Defines a list of commands to be executed before COMMENT text -if any- is displayed.
|
| ACOMMANDS |
Defines a list of commands to be executed after COMMENT text -if any- is displayed.
|
Zone block
| LIMITS |
Defines rectangular interactive area on screen.
|
| LABEL |
Text to be displayed when mouse enters the area defined by LIMITS.
|
| FLAGS |
One or more among behavior flags, separated by pipe character.
|
| COMMANDS |
List of commands to be executed when zone is activated.
|
| MOVETO |
Specifies position (x, y) character is set to walk to when action is triggered on this zone.

Animation block
| POSITION |

Data file holding animation frames and respective sizes.
|
| SCRIPT |
Name of script file (SCR) containing instructions to drive this animation (and possibly others).
|
| LABEL |

| FLAGS |
One or more among behavior flags, separated by pipe character.
|
| COMMANDS |
List of commands to be performed when execution of animation script (SCR) is over.
|
| MOVETO |
Specifies position (x, y) character is set to walk to when action is triggered on this animation (usually a non-playing character).

|
| ENDNODES |
Marks the end of Nodes block.
|
Commands/Acommands block
This block holds a list of commands with their own parameters. With regard to the order in which commands are encountered during parsing, the execution flow is backwards.
| SET |
Sets a global (system) flag or a flag declared with LOCALFLAGS statement.
|
| CLEAR |
Clears a global (system) flag or a flag declared with LOCALFLAGS statement.

|
| SPEAK |
