Key to Table 4-7-1: Predefined Fields Attributes

Chapter 4-7: Predefined Fields and Processes

The following table specifies the attributes of each APPX predefined field (PDF). The following items are included in the table:

· The PDF name, which is the exact name of the PDF as you would specify it in a statement.

· The size of the PDF.

· The sign, indicating if the PDF is a signed value.

· The storage type, or how the PDF value is stored.

· The IPC characteristics, provided in the following three columns:

· Pass—the extent to which the PDF value is passed to other processes.

· Rec—the extent to which the PDF value is received by other processes.

· Share—the extent to which the PDF value is shared with parent processes.

The following abbreviations are used to describe the IPC Characteristics:

· sub —communicated with subprocess invocations.

· manual—must be manually communicated with statements.

· prohib—communication is prohibited.

· rcv—communicated with any fully or partially receptive process.

· rel/sub—communicated with all subprocess and related invocations.

· all—communicated with all invocations regardless of the receptivity level.

· Modifiable?—tells whether the PDF value can be changed with statements.

· Initial value—(how the PDF is initialized). When this column contains an asterisk (*), the PDF initial value is controlled by values entered in system administration or at runtime by a user.
