Entry
Explanation
Blank
This data structure is not a program status or data area data structure, and this data structure is not globally initialized.
I
Data structure initialization. All subfields in the data structure are initialized; characters to blank, numerics to zero, in the order in which they are defined, during program initialization.
S
This data structure is the program status data structure. Only one data structure can be specified as the program status data structure.
U
This is a data area data structure. The external data area (named in positions 7 through 12) is retrieved when the program starts and rewritten when the program ends. If you put blanks in positions 7 through 12, the local data area is used.
