50 Chapter 3 Using Published Displays on the Web
Note This applies to InTouch tags and Galaxy attributes only.
Values are written back immediately to custom properties during
script execution.
Example
dim i as integer;
ud1.int1 = 0;
for i = 1 to 100
ud1.int1 = ud1.int1 + 3;
next;
In the example, zero is not written back to the Galaxy
attribute ud1.int1 during script execution. Instead an
internal “invisible” variable is used instead of the actual
reference during script execution.
This variable is increased 100 times by the value of 3, the
result is then written back to the actual Galaxy reference at
the end of the script execution.
In other words, the value 300 is written back to the Galaxy
reference ud1.int1 one time at the end of the script execution.
