If you migrate from Version 6 or earlier of TP1/Message Control and the architecture is not 32-bit, you must check the C language source files. This appendix lists the changes to the interfaces from when migrating from Version 6 or earlier.

The following table provides an overview by interface of the changes that are explained in this appendix.
