Actions

There is an ASCII syntax for every state table action described in Prompt statements. In most cases, the name of the action is the same. The syntax of the state table actions includes:

• A label, to identify the action (optional)
• A description of the action (optional)
• Parameters which must be coded in the order specified in Prompt statements, under “ASCII Syntax” for each action
• Edges, possible results, with the label of the action to proceed to next.
• A semicolon (mandatory)

The labels, descriptions, comments, parameters, and edges can be coded like this:

label: "state description"

  action(parms)

    edge edgename:  label

    edge edgename:  label

    <...>

;    # comment ; indicates end of state

Note that the label, description, and comment are optional.

For example:

start: "get input from caller"

   GetData(buffer1, 12, 25, 10, 5)

     edge EDGE_GETD_LEN_OK:      play_voice

     edge EDGE_GETD_TOO_SHORT:   start

     edge EDGE_GETD_TOO_LONG:    start

     edge EDGE_GETD_INCOMPLETE:  start

     edge EDGE_TIMEOUT:          start

     edge EDGE_LAST_TIMEOUT:     last_timeout

     edge EDGE_HUP:              hup

;    # end of GetData 

There is an example of coding for each action in Prompt statements. The examples use the convention that names of string variables are in uppercase.
