Extended source format is introduced in COBOL for AIX, V4.1. The new extended source format is divided into distinct areas as before, but permits lines varying in length from a minimum of 0 bytes to a maximum of 252 bytes. The following figures illustrate the key difference between the two formats: Fixed source format: Extended source format: For both formats, lines shorter than the maximum length are logically extended with space to the maximum length. You can use the SRCFORMAT option to indicate whether your COBOL source... [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]
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 Outdated...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]
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]

Though it has been half century that COBOL has been around, it is still the most dominant language for running business-critical applications, and it is the backbone for organizations everywhere. Among them, a majority of the business transactions processed by COBOL run on IBM System z hardware. Given this , IBM is making a latest refresh to this venerable language on z/OS, the V5.1 release will go alive on June 21! Generally speaking, IBM says the Enterprise COBOL for z/OS, V5.1 compiler will give applications a 15-20 percent... [More]
In addition to the fixed indicators that can be specified in the indicator area of the source reference format, there is a new floating comment indicator (*>) introduced by COBOL for AIX, V4.1. You can use the floating comment indicator in both the extended format and in the fixed format. A comment indicator indicates a comment line when specified as the first character-string in the program text area (Area A plus Area B). It can also indicate an inline comment when specified following one or more character-strings in the program text area.... [More]

Enterprise COBOL for z/OS V5.1 was announced on April 23, 2013 and became generally available on June 21, 2013. This new compiler was re-architected to include an advanced technology framework for optimizing COBOL applications and exploiting z/Architecture, including the latest zBC12 hardware, providing significant performance improvements over Enterprise COBOL V4. These performance improvements will reduce CPU utilization and lower operating costs for customers running business critical applications. Enterprise COBOL... [More]
