[S7] String data type as in/out parameter

Hi

is it possible to use strings as in/out parameters for an FC block in S7. i am trying to make an FC that searches for a specific code in a stringm and gives back a value that belongs to that code.

but i cant use the variables in the standard FC blocks that are available for strings ( like find, mid, insert, ...)

Can you write the pseudo-code for the specific processing you require.
