Advanced Functions

You will appreciate that within your chosen activity, there will be that activity’s unique events

and possibly also a variety of unique resultant event permutations depending on how the

activity develops�

If you were to code every Event or Tag and the total number of resultant Event or Tag

permutations for each into a CODA Form, the size of the Form would have the potential to

be large; and the ability to rapidly nd and activate and deactivate each Tag or Event with its

resultant Popup Tags and record them, (in real time,) could become impractical�

One solution to this is to have individual coding personnel coding a very focused facet of the

activity with a greatly simplied template� Another solution is to incorporate a mechanism

where code buttons can be automatically activated and/or deactivated in the CODA Form by

establishing links between selected buttons�

9� Links

A Link is used to automatically activate or deactivate buttons in a CODA Form as a consequence

of how the activity is unfolding� A link may also pass Tag information from a source Tag to a

target Event when the link activates or deactivates the target Event�

The benet of using Links is to reduce the number of manual button activations and/or

deactivations, (clicks) that an operator would need to perform� The use of links in the Form will

make the coding of your activity more ecient�

Links can be initiated when an Event, Tag or Popup Tag button is activated (button clicked down)

or when an Event button is deactivated (button clicked up)�

a� Link Protocols

A Link may be used to “activate” , “deactivate” or to “reactivate” a button�

A Link will not be activated unless the Source button is active�

A Link to a Tag button may tag or pass its tag as well as activate the button�

A link will only work in the direction of the link�

A link may be established

– from an Event button to another Event button or to a Tag button

– from a Tag button to an Event button or to another Tag button

– from a Popup Tag button to an Event button or to a Tag button

A Link cannot be established :

– from an Event button to a Popup Tag button

– from a Tag button to a Popup Tag button

– from a Popup Tag button to a Popup Tag button
