TRANCOMP/XL by May Lee--Santa Clara Information Systems Division A Native Mode version of TRANCOMP/XL A.08.03 is now available with XL Release 2.2. With TRANCOMP/XL you can compile TRANSACT source code into TRANSACT p-code. The TRANCOMP/XL filename is TCOMPXL and is a component of TRANSACT/XL A.03.01 and cannot be ordered separately. TRANCOMP/XL uses Native Mode Heap Space instead of the Compatibility Mode Stack to provide more space for a user program's internal tables. Thus, TRANCOMP/XL can compile larger programs and the need for segmentation can be reduced. TRANCOMP/XL will be invoked by TRANSACT/XL A.03.01 to create a temporary IP file that is then read by the TRANSACT/XL compiler. TRANCOMP/XL can also be run standalone to create an IP file. This IP file can either be run by the TRANSACT/V processor (in Compatibility Mode) or be compiled by the TRANSACT/XL compiler into a Native Mode object file. TRANCOMP/V is still available and should be used for programs that need to run on both MPE V and MPE XL. This is to ensure that stack size limits are not exceeded since TRANCOMP/XL may create IP files that are too large to be run through TRANSACT/V. A new compiler option has been added in order to allow programmers to choose between Compatibility Mode TRANCOMP and Native Mode TRANCOMP when running TRANSACT/XL. This option is recommended for applications that need to run on both MPE V and MPE XL. The option "CM_TRANCOMP" will instruct TRANSACT/XL to use Compatibility Mode TRANCOMP. The default for TRANSACT/XL is to use TRANCOMP/XL. TRANCOMP/XL will reduce the need for segmentation but will not eliminate it. For very large applications, segmentation will still be necessary when the following limits are approached: * NUMBER OF P-CODES 16,383 * MAXIMUM DATA REGISTER SIZE 134,217,727 The maximum number of items and literals depends greatly on their size and on the type of statements used in the program. The following guidelines can be used: * NUMBER OF ITEMS 3,200 * NUMBER OF LITERALS 3,200 The above is a general guideline and is not absolute. For example, users may or may not be able to declare 3,200 items depending on the amount of internal space that is already used by the compiler.
