You will want to use the BoTran2ReportLang template with a pause control.

Here is an example of the control dropped in below a wizard generated report using all keys.

Reposition as you see fit.<g>  Put your languages into the radio fields. 

The Save Me checkbox will save the language choice to an ini file, and automatically preselect that language the next time the report is run.

The template prompt only has one checkbox to disable the template if you suspect problems.

Here is a screen shot of the control at runtime with a standard pause control.
