Scripting a Field

You must lock the field for it to work then click any line of the field

Copy and paste the script below into the field script and make sure that the field is locked

Now try it out.

The key to this setup is these lines in the field script

put word 2 of the clickLine into lino
do line lino of cd fld 1

lino is a variable (a temporary container in this case)

the clickLine is a function peculiar to fields. It returns the line number and the field name containing the text in a field last clicked on by the user.

do is a keyword that carries out a SuperTalk statement

select the clickLine does the highlighting when the text is clicked on.

Fields that do things when you click on the individual lines are often used in SuperCard for such things as indexes.

For instance if you put all the card names of a project in such a field they can be used to take the user to each card as they select its name from the index field.

Make a button under the field and type this script into it

When it is clicked the do keyword runs through the contents of the field statement by statement. The statements have to be separated by a return i.e they must be on separate lines. The statements can be in any container, a field , or a variable and they act just like script would that was made up of the same lines or statements.
