Using the format-1 global area by applications

The format-1 global area is designed primarily to be used by applications, although the control program does access it. Application programs that access or update the format-1 global area must meet certain requirements. Several application programming macros are available to application programmers to satisfy these requirements. The examples presented in this section are only illustrations; they are not the only solution to a coding problem. You can find a complete description for each macro in z/TPF General Services.
