- PROCEDURE ICA(GetPut : boolean;
- var SourceDest);
- { DESCRIPTION:
- Gets or puts information in the Intra-Application Communications Area (ICA).
- SAMPLE CALL:
- ICA(True,MyVar);
- or
- ICA(False,MyVar);
- RETURNS:
- See notes (bellow).
- NOTES:
- These sixteen bytes, called the Intra-Application Communications Area
- (ICA) can be used by any program for any purpose, Usually it is used
- to pass data betwenn two or more programs. Not many programs use this
- area. If you wish to use this area, make sure checksums and signatures
- are used to insure the reliability of your data, since another program
- may also decide to use this area.
- [in The Assembly Language Database, Peter Norton]
- The incomming SourceDir variable may be of any type.
- Nevertheless, the size of that variable MUST be at least 16 bytes long,
- or unpredictable results may occur...
- The programer before changing this area contents, should keep its
- contents in a variable for later restore. It is not a very good ideia
- to not restore the contents before the program end, because that
- area may being used by another program. }

- BEGIN { ICA }
- if GetPut then
- Move(Mem[$0000:$04F0],SourceDest,16)
- else
- Move(SourceDest,Mem[$0000:$04F0],16)
- END; { ICA }
