PREFACE

This manual i s written for the prospectiveoperator of the GE-225 Information Processing System. It i s assumed that the operator has already had a GE-225 programming course. Much of the basic information about computer instructions and programs i s touched upon only briefly, for i t i s intended that the GE-225 Programming Reference Manual be used a s a sup- plemental text.

Additions and modifications continue to be made to the GE-225 System, therefore, this manualis designedfor use in a loose-leaf notebook, and pages a r e numbered by chapters to permit additions and changes to be easily made.

The majority of the information in thismanualpertains to GE-225 equipment in general, and i s applicable to most models now in use. As required, more specific information will be added for particular models, and the information will be identified by model number.
