IXLLSTE, IXLLSTM, and IXLLSTC are interfaces to list services that were made available in OS/390® Release 9. The three macros collectively provide the same functions available with the IXLLIST macro, and will replace the IXLLIST macro for future enhancements. The IXLLIST macro will be maintained; however, it will not be updated with any new support after OS/390 Release 8.

The new list services macros contain updated syntax and may contain keyword names that are changed from those used in the IXLLIST macro. Applications using IXLLIST can be changed to an equivalent IXLLSTE, IXLLSTM, or IXLLSTC service. For compatibility, however, when running on systems at OS/390 Release 8 and lower, the application using the new services cannot make use of any of the new function available only at OS/390 Release 9 and higher.

Using List Services (IXLLIST) describes list services and the functions provided by IXLLIST. None of that information is negated by the new list services macros. Therefore, this topic, “List Services (IXLLSTC, IXLLSTE, IXLLSTM)”, concentrates on the new functions introduced by the macro interfaces to list services, as well as providing guidance in the use of the three new macros.
