Removing Obsolete Features The features listed below are obsolete in HP Business BASIC/XL. Most of these features are obsolete because of architectural differences. Remove them from your applications to avoid problems. USLINIT and SEGMENT Since USL files and SEGMENTs do not exist in MPE XL, these two compiler options have no meaning. They cause warning messages. BB'MERGE'IT and BB'SORT'IT BB'MERGE'IT and BB'SORT'IT are SPL external routines in SL.PUB.SYS. BB'MERGE'IT and BB'SORT'IT are available for compatibility mode programs. These two routines are not necessary in HP Business BASIC/XL because SORT and MERGE intrinsics do not interfere with HP Business BASIC/XL. Users can declare SORTINIT and MERGEINIT intrinsics directly in HP Business BASIC/XL programs. BB'SORT'IT and BB'MERGE'IT are unnecessary. Native mode SORT intrinsics are also available on the MPE XL machine. These intrinsic names are the same as those on the MPE V machine except that they have "HP" prefixes: HPSORTINIT, HPSORTEND, HPMERGEINIT, HPMERGEEND.... Refer to the SORT/MERGE XL Reference Manual for more information about these new routines. The native mode SORT and MERGE intrinsics have different parameter lists that require source file changes. EXTERNAL SPL MPE XL does not support SPL or FORTRAN 66. There are two options for SPL and FORTRAN 66 external routines: 1. Rewrite in a native mode language. 2. Call by using a switch stub for each routine. Supported languages include: * HP FORTRAN/XL * HP C/XL * HP Pascal/XL * HP COBOL II/XL Before rewriting these routines in another language, check to see if HP Business BASIC/XL offers the capability provided by the routine. Refer to the Switch Programming Guide for information about the switch subsystem and programmatic access through switch stubs. OPTION VARIABLE Business BASIC/V programs can call MPE V intrinsics that are defined as OPTION VARIABLE and SPL external routines that are OPTION VARIABLE. MPE XL doesn't support OPTION VARIABLE. Default parameter values and a new Pascal option (OPTION EXTENSIBLE) can replace OPTION VARIABLE. OPTION EXTENSIBLE allows extensible parameter lists. Refer to the HP Pascal Programmer's Guide or the MPE/XL Intrinsics Reference Manual for more information about OPTION EXTENSIBLE.
