Dynamically increasing profile

Hello,

I am looking for a way to have a profile that increases itemcount during its duration. Currently I have seen this in several profiles:

Code:

<!DOCTYPE Profile [
	<!ENTITY SomeVariableName "100">
]>
<If Condition="ItemCount(x) &lt; &SomeVariableName ">
 "do something"
</If>

What I am looking for is a way to increase "SomeVariableName" lets say by 100 again. Or to have something else that would increase the count during its runtime.

Something like

Code:

declare SomeVariableName 100 
<If Condition="ItemCount(x) &lt; &SomeVariableName ">
 "do something"
 SomeVariableName = SomeVariableName + 100
</If>

I have no idea how to express it in the language the bot is using.
