When generating an experiment, E-Studio will fail with an error if any User Script, etc has an Option Base 1 or Option CStrings Off script encountered.
E-Basic relies on array values being zero index based. In addition, Option CStrings On is required by E-Basic to permit c-style escape characters for \n new lines.
E-Studio catches attempts to change the Option Base or Option CStrings value to avoid potential issues with experiment logic.
NOTE: Collection objects in E-Basic are always 1-based and are not affected by Option Base.
