General Macros Introduction

In the TPF environment, macro is a generic term that covers several types of user services. Macro definitions are used to generate the requests for the TPF system online control program services. Such a request is normally expanded into an SVC instruction and necessary parameters, which are ultimately interpreted by the TPF system service routines invoked by the online macro decoder. For example, a FINDC macro request processes an application (Entry) to have the system obtain (find) a record from the online DASD files.
