With COBOL for z/OS, V5.1, you can use the ARCH option to specify the machine architecture for which your executable program instructions are to be generated. The syntax is ARCH( n ). Parameter n is an integer between 6 and 10 inclusive, specifying the machine architecture for which instructions are to be generated. ARCH(6) is default. If you specify a higher ARCH level, the compiler generates code that uses newer and faster instructions. Your application might abend if it runs on a processor with an architecture level lower than what you... [More]

When you're doing z/OS maintenance and production support tasks you will routinely have to do two fairly involved analysis processes: Control Flow Analysis - where you build a "mental map" of how the PL/1 procedures and functions, COBOL paragraphs and sections or HLASM routines hang together via the operational control flow constructs in the code (PERFORM, etc.). "in the code" - means from the source code only. Data Flow Analysis - where you need to trace the flow a value within one or more programs - as it's... [More]
In COBOL, one may write invalid programs or use invalid data in program which can be compiled and executed but lead to technically incorrect or even unexpected results. It's the responsibility of the COBOL programmer to make sure that programs and data are valid, and as the behavior of invalid programs (or programs with invalid data) is undefined, IBM makes no guarantees that the result in these cases won't change between compiler releases or even PTFs. While migrating from Enterprise COBOL V4.2 to Enterprise COBOL V5, some users... [More]

To define variable length tables in COBOL, we usually specify the OCCURS ... DEPENDING ON clause in the data description entry for an item contained within a group structure. While this defines an item with a variable number of occurrences at run time, in earlier versions before Enterprise COBOL V5.1, we also need to specify a maximum number of occurrences in the syntax , and hence a maximum size for the table and the containing group, which causes usability problems in some contexts. In particular, this problem occurs when defining... [More]

In IBM mainframes, the queued sequential access method (QSAM) is widely used as an access method for files, or more properly data sets. But it has not been implemented in AIX systems. In COBOL for AIX, V4.1.1, a new file system, QSAM file system , is introduced to improve the file input-output performance. You can transfer QSAM files from the mainframe to AIX without the need to compile with -qhost . Simply use the FTP commands binary and quote site rdw . An exception here: If the file contains EBCDIC character data, compile the AIX COBOL... [More]

With Enterprise COBOL for z/OS V5, the new STGOPT option can be used to control storage optimization. This option syntax is as follows: .--STGOPT--. >>----------NOSTGOPT------------------------>< NOSTGOPT is the default option. SO is the abbreviation for STGOPT and NOSO is for NOSTGOPT. If STGOPT is specified, the compiler will discard any or all of the following data items, and will not allocate storage for them. Unreferenced... [More]
This is the sixth in a series of blog entries on the subject of debugging IBM Enterprise COBOL for z/OS V5.1 using Debug Tool. These blog entries point out some of the improvements you'll see compared to debugging earlier versions of Enterprise COBOL. This blog entry is regarding Debug Tool's support for COBOL data types.

In particular, commands which perform assignment, such as MOVE, and commands which... [More]
In earlier versions of COBOL for AIX, WSCLEAR cleared all of a program's WORKING-STORAGE data items. Beginning with Version 4, WSCLEAR clears a program's non-EXTERNAL data items in WORKING-STORAGE to binary zeros at initialization. With COBOL for AIX, V4.1.1, you can use WSCLEAR with a new suboption, nnn (an integer between 0 and 255), to initialize each byte of WORKING-STORAGE data to a specific value. The storage is initialized before any VALUE clauses are applied. See the syntax of WSCLEAR below: >>-------... [More]

z/OS supports simplified processing of multiple versions of related data. The sequences of different generations of data or updates to the data are known as generation data groups (GDGs). Each data set in the group is called a generate data set (GDS) or simply generation. On AIX, “file” is the equivalent term for “data set” on z/OS. Grouping related files offers the following advantages: All of the files in the group can be referred to by a common name The files in the group are kept in generation order. Outdated... [More]
COBOL for AIX version 4.1 introduces a new utility, the source conversion utility (scu), to assist the conversion of programs in non-IBM COBOL source formats. The main function for utility is to “normalize” COBOL source input text so that the resulting output source text can be compiled by IBM COBOL for AIX V4.1. The input formats that are specifically addressed are some non-IBM fixed-format source and COBOL standard free-format source. The individual transformations done by scu includes the following: Converting... [More]
In the past, due to the Information Center (IC) restrictions, the GAed docs cannot be refreshed until the next major release, which took years. Earlier this year, IC was replaced by Knowledge Center (KC), and with the enhancements provided by KC, we are able to refresh the online docs as needed to make sure that they are accurate and up to date. For now, we plan a quarterly KC refresh after the GA date of a major release. Notes: Only the latest GAed docs will be refreshed, docs for earlier releases will not. Because of form number controls, the... [More]
