They agreed unanimously that more people should be able to program and that the new language should not be restricted by the limitations of contemporary technology.
A majority agreed that the language should make maximal use of English, be capable of change, be machine-independent and be easy to use, even at the expense of power. The short-range committee was given to September three months to produce specifications for an interim language, which would then be improved upon by the other committees.
Work began by investigating data description, statements, existing applications and user experiences.
While some members thought the language had too many compromises and was the result of design by committee , others felt it was better than the three languages examined. Some felt the language was too complex; others, too simple.
Such features included boolean expressions , formulas and table subscripts indices. They fell short of expectations: Joseph Wegstein noted that "it contains rough spots and requires some additions", and Bob Bemer later described them as a "hodgepodge". The subcommittee was given until December to improve it. Despite being technically superior, FACT had not been created with portability in mind or through manufacturer and user consensus.

Designing My First COBOL Program
The following sections describe the details of layout specification. You can also think of a column as a character. Columns are segmented into groups, with each group serving a particular purpose. The columns groups are as follows: Columns is the group in which a programmer defines a sequence number.
A sequence number is similar to a line number.
Column 7 is reserved for special characters. Columns is called Area A. Columns , also known as Area B, is where you write code statements. Columns is reserved for developer use.

You can write poetry in there, if you so desire. Figure 3, below illustrates the columns grouping described above. If there is a violation, the compiler will error.
Compilation is the process of taking textual source code and converting into a binary format that the computer can understand. For example, how a compiler orchestrates the way numbers are loaded and then computed in memory matters a lot!
A good compiler will make code run really fast. IBM has been in the COBOL business for a long time and has a keen understanding about making compilers that are fast and cost-effective. For example, the z14 System compilers improve efficiency by taking advantage of almost 24 new low-level instructions.NET Framework portal.
The report writer statements are covered in the report writer section. Whether you're a beginner or a professional, you'll boost your productivity by using these as models when you create or maintain COBOL programs.
We shortened it and got rid of a lot of unnecessary notation.
To specify a particular data item, for instance one of the items contained within the sale-date group, the programmer would use the-year IN sale-date or the equivalent the-year OF sale-date.
