The following code fragment prompts the user for input.
If the input string is the string true, the code fragment
writes the message You typed TRUE on the host screen. If
the input string is any other string, the code fragment writes the
message You typed FALSE. This example uses the following
actions: Prompt action, Condition action, and Input action.
You can copy this code fragment from this document into the system
clipboard, and then from the system clipboard into the source view.
Because this code is a fragment, you must copy it into a macro screen
in an existing macro script. You must also create a string variable
named $strData$. To create the variable, add the follow lines after
the <HAScript> begin tag and before the first <screen> element:
After you save the script in the macro
editor, you can edit it either with the macro
editor or in the source view.
Notice the following facts about this example:
The example consists of one code fragment containing an <actions>
element and the actions inside it.
The first action is a Prompt action that displays a message window
and copies the user's input into the variable $strData$, without writing
the input into an input field in the session window.
The first part of the condition action (the <if> element) contains
the condition, which is simply $strData$.
Because $strData$ is a string variable in a boolean context, the
macro runtime tries to convert the string to a boolean value (see Automatic data type conversion). If the user's input is the string 'true' (in
upper, lower, or mixed case), then the conversion is successful and
the condition contains the boolean value true. If the user's input
is any other string, then the conversion fails and the condition contains
the boolean value false.
If the condition is true, then the macro runtime performs
the action inside the <if> element, which is an Input action writing
the message You typed TRUE on the host screen. When all
the actions inside the <if> element have been performed, the macro
runtime skips over the <else> action and continues macro processing.
If the condition is false, then the macro runtime
skips over the actions in the <if> element and begins performing
the actions in the <else> element, which includes one Input action
that writes the message You typed FALSE on the host screen.
After performing all the actions in the <else> action, the macro
runtime continues macro processing.
