action = "(string)";

Execute this LISP function.

This attribute is a callback that executes a LISP function when the user clicks a given tile.

For string, specify the name of a LISP function.

Example

action = "(function)";

NOTE

Note that the tile action, known as a callback function, is more usually specified by the controlling program using the action_tile function. If an action is defined by the calling program, the DCL-specifed action is ignored.
The action attribute cannot call an SDS function.
A tile can have only one action assigned to it, and action_tile overrides action if assigned by the program.
Do not include the sds_command function in the action function.
