{ These are preprocessor statements, which are not executed at runtime. |
4 |
They are instead processed at early parser stage. You can set a |
5 |
preprocessor condition with: |
6 |
|
7 |
SET_CONDITION(<condition-name>) |
8 |
|
9 |
Then you can use such preprocessor conditions to conditionally let the |
10 |
script parser know which code parts shall be used and which code parts |
11 |
shall be ignored. The ignored code parts will never be executed and thus |
12 |
will not waste any resources at runtime. |
13 |
|
14 |
There are also built-in conditions, already defined by the sampler, which |
15 |
allows you to execute script parts depending on certain circumstances. |
