How to create user-defined variables in Adobe Captivate

Like all programming languages, Captivate uses variables to temporarily store values, which can be used by other components of Captivate. In Captivate, there are two types of variables, system and user-defined.

System variable: System variables come pre-defined with your copy of Captivate. For example, cpCmndMute, which mutes the audio in a slide. For a list of all system variables, see Captivate variables list.

User-defined variable: These are variables that you can create and assign them to customized actions. The name you assign to a user variable must not conflict with Captivate’s internal functions, reserved keywords, exposed system variables, or other hidden variables.

There are some conventions while naming a variable. They are:

Do not begin the name with a blank or a numeric character.
Do not use any reserved keywords. The table below displays variable names that are reserved by ActionScript.
Use unique variable names.
Use intuitive names for a variable.
Always add descriptions to a variable.

In this example, we will create a user-defined variable and associate the variable with a button. When you click the button, a name displays.

Click Project > Variables. The Variables dialog-box displays.

To add a variable, click Add New, and enter the variable information in the Name, Value, and Description fields.

Name: Specify a unique name for the variable. Ensure that the name is intuitive enough to help users guess its content. For example, a variable storing the version number of a product would have the name ProductVersion or VersionNumber.
Value: Specify a value for the variable. The value that you specify occurs at all instances of occurrence of the variable in the document. You can also choose to set the value later by leaving this field blank. Variables with undefined values appear as blank spaces in the project.
Description: Optionally, add a description for the variable. For example, you could add a note for the authors instructing them about when to use the variable.

To save the changes, click Save.

In the Captivate project, insert a button, a text entry box and a text caption, as shown below:

In the text entry box, you insert the variable you had created, as shown below:

With the cursor after the “:”, click [X] in the Property Inspector, as shown below:

Also, make the text caption hidden.

After you click Insert Variable or [X], in the Insert Variable dialog, click the Variables drop-down list, and choose the variable you created.

After you insert the variable, the variable name gets enclosed within $$...$$, as shown below:
