Comp and Comp-3
In real time in which situations we can use comp-3 and comp. What is the major difference between these two?
ramesh4greek
- Jun 11th, 2010
In COMP the data is stored in binary format, and displayed in character format.In COMP3, the data is stored as the above formula. For lower bound values COMP is best and for upper bound values COMP3 is better.

COMP Usage is used for data items of numeric type. There are 4 types of COMP usage.
1.COMP : Used only for integers.Either half word or full word .
2.COMP -1 :Used for floating points.Internal representation is hexa decimal.full word is used.No PIC Clause .
3.COMP -2 : Similar to COMP-1.Only difference is double word(8 bytes )is used
4.COMP -3 :Interenal representation is decimal.Each character is assinged to half byte.The sign bit is assinged to right most bit. The no.of bytes required for n characters is (n/2) + 1 (rounding down)akhileshrewa

Is Renaming variable takes separate space or not

Can we use search and search all in embedded sql?
TheMadProfessor
- Oct 12th, 2009
SEARCH and SEARCH ALL are only used for tables within the program and have nothing to do with SQL. SQL is used for queries and other such functions on external relational tables maintained by a DBMS.
Senijor Mastrojani
- Oct 24th, 2006
search and search all are cobol reserved words.sequal will not recognize them wether it's embeded or not.moreover it makes no sence for instance to fetch everything onto file and than use search or search-all when from database you can select anything randomly.

Could you please let me know what is the procedure you are following to find the errors?krishna

Compilation converts the source code in to object code but the object code is not executable in mainframe environment so we need to link-edit it by using iewl............compilation is must for the programs to execute...............

What is the difference between comp and comp-3 usage? Explain other COBOL usages?
Comp is a binary usage, while comp-3 indicates packed decimal. The other common usages are binary and display. Display is the default. 3/28/00 Dave Herrmann: 'I was reading your FAQ on Cobol, as an fyi Comp is defined as the fastest/preferred numeric data type for the machine it runs on. IBM Mainframes are typically binary and AS400's are packed.'
