%AINT

The %AINT command can be used to specify whether AID is to work with 24-bit addresses or 32-bit addresses for indirect addressing. For AID, the address before the pointer operator (->) then consists of 24 or 31 bits accordingly.
The addressing mode for the test object is not affected as a result.

• aid-mode specifies the mode of address interpretation for indirect addressing within an AID work area. 

Command	Operand
%AINT	[aid-mode] [,...]

As the default, AID interprets indirect address specifications according to the current addressing mode for the test object. Specification of %AINT with the keyword %MODEn deactivates automatic adaptation in this way. The test object4s addressing mode can be interrogated with %DISPLAY %AMODE. It can be changed with %MOVE. %SHOW %AID or %SHOW %BASE reveals the addressing mode valid for the current AID work area, in addition to other information.

If no qualification is specified, %AINT applies to AID commands which reference or use indirect addresses in the current AID work area.

An %AINT without operands switches back to the default address interpretation. The same effect is achieved by %AINT with a base qualification and without %MODEn. Otherwise the declared addressing mode applies until /LOGOFF or /EXIT-JOB.

%AINT does not change the program state.

aid-mode

defines how indirect addresses are to be interpreted in subsequent AID commands, applicable in the current AID work area or the work area identified by the specified base qualification.

If a keyword is specified for address interpretation but no qualification is specified, the %AINT command applies to the processing of the current AID work area.

If a base qualification is specified but no keyword for address interpretation, the default AID address interpretation applies in the corresponding AID work area.

• If a period is placed at the beginning, it is an identifier for a prequalification. It must have been defined via a previous %QUALIFY command.
  A period must be placed between a base qualification and the keyword for address interpretation.

E={VM|Dn}

This is specified if it is not intended that the change in address should apply to the current AID work area. If only a base qualification is specified, the default address interpretation applies again for the area which this addresses.

{%M[ODE]31 | %M[ODE]24}

Keyword specifying how many bits are to be taken into account in indirect addressing in AID commands.

%M[ODE]31 %M[ODE]24

31-bit addressing. 24-bit addressing.

Examples

The contents of address V’100’ are: 1200000C
The contents of register 5 are: 010001A0

1. %AINT %MODE24
%DISPLAY V'100'->
%MOVE %5-> INTO %5G

   The %AINT command has the effect of switching to 24-bit address interpretation.
   The switch applies to the current AID work area.
   The %DISPLAY outputs 4 bytes starting at address V’00000C’.
   The %MOVE transfers 4 bytes starting from address V’0001A0’ to AID register 5.

2. %AINT %MODE31
%DISPLAY V'100'->
%MOVE %5-> INTO %5G

   Address interpretation for the current AID work area is switched to 31-bit interpretation.

   The %DISPLAY outputs 4 bytes starting at address V’1200000C’.
   The %MOVE transfers 4 bytes starting at address V’010001A0’ to AID register 5.
