INT32INDEX Directive

INT32INDEX generates INT(32) indexes from INT indexes for accessing items in an

extended indirect structure in a D-series program.

The default is NOINT32INDEX.

Usage Considerations

This directive can appear in the compilation command or any number of times in a D-

series compilation unit.

INT32INDEX turns the INT32INDEX setting on for subsequent declarations.

NOINT32INDEX turns the INT32INDEX setting off for subsequent declarations. Such

declarations retain their INT32INDEX or NOINT32INDEX attribute throughout the

compilation.

PUSHINT32INDEX pushes the current INT32INDEX setting onto the directive stack

without changing the current setting.

POPINT32INDEX removes the top value from the directive stack and sets the current

INT32INDEX setting to that value.

INT32INDEX

INT32INDEX generates an INT(32) index from an INT index for a structure item in an

extended indirect structure. INT32INDEX thus produces a correct extended offset even

when the word offset of the structure field (from the zeroth structure occurrence) is

greater than the signed INT range (–32,768 through 32,767). (For a STRING item or a

substructure, the byte offset must be in this range.)

INT32INDEX overrides the INHIBITXX or NOINHIBITXX directive.

NOINT32INDEX

NOINT32INDEX produces code that is faster than that produced by INT32INDEX, but

it produces an incorrect extended offset when the offset of the structure field is outside

the signed INT range. In such cases, you must use INT(32) indexing as discussed in

Section 8, “Using Structures,” in the

TAL Programmer’s Guide.
