You have to use textual_implementation and textual_declaration properties of IScriptTextDocument.

There are few methods like replace, insert, append and so on (see ScriptEngine.chm for more information).

proj = projects.primary
found = proj.find("Application", True)
app = found[0]
\# Create FB
mypou = app.create_pou("MyPou")
\# Change declaration of the FB
implementation = mypou.textual_declaration.replace("""FUNCTION_BLOCK MyPou
VAR_INPUT
   iValue : INT;
END_VAR
VAR_OUTPUT
END_VAR
VAR
END_VAR""")
\# Change implementation of the FB
mypou.textual_implementation.replace("""iValue := iValue + 1;""")
\# Add method to FB
dosomething = mypou.create_method("DoSomething", "INT")
\# Change declaration of the method
dosomething.textual_declaration.replace("""METHOD DoSomething : INT
VAR_INPUT
   iVal1 : INT;
   iVal2 : INT;
END_VAR""")
\# Change implementation of the method
dosomething.textual_implementation.replace("""DoSomething := iVal1 + iVal2;""")
\# Find the pou and delete it
found = app.find("MyPou")
if found and len(found) == 1:
   found[0].remove()
else:
   print("POU 'MyPou' was not found"

Hello!

Is it possible to write a simple Codefragment, something like "count := count + 1; etc.. " including creating the variable count over a Python Script?

I already have written a script which creates a POU (ST), but i can not find any topics about writing an application over a script.

Regards!
