how to write a rollback into a program with isam and MS SQL

I am in Visual Studio 2010; Visual Cobol 2.0.  We are converting some of our ISAM files to MS SQL.  I am testing out a proof of concept that a single program can handle rollback of isam files and MS SQL tables. What I have tested; it does not. The SQL did not rollback nor did the ISAM get added back in from the delete. Can a COBOL program rollback handle both types of files. If it can, what is the necessary rollback statement or compile directives that are necessary??????        Background we are try to see if a transactional ISAM file is needed to become MS SQL table.
