But each logical file that you create must be maintained by the operating system each time a record is added or deleted to the file. It reads in the data from the joined files very similar to reading a record from one file in RPG or Cobol. The first two do not require making any changes to application code. RPG needs to know 2 things about a read statement: 1) what file to read 2) what indicator to turn on if there was not a "next" record in the file (that is, what indicator will tell you that there is no more data in the file) Indicators are numbered from 01 to.

Read the LSEQ file and write an RSEQ, ASCII File. then i have to write it in to the out put file. Net that will easily allow me to do this?. When there are too many records for method 3 to be effective, you might write a COBOL program to read all the related records into memory, then write a completely new output record. A Cobol Copybook is a textual description about the file structure and is commonly used in mainframe environments often.

But for only reading fixed length cobol file do I still need PWX or it can be read using powercenter only?Also is there any documentation to read about power exchange for COBOL file. An image can be basic, with nothing but the operating-system fundamentals, or it can consist of a sophisticated pre-built application stack ready for launch. Effectively, with your INTO you were copying the data to itself, the results of which are "undefined" in the COBOL Standard, but likely are reliable (although pointless) within a particular compiler. - When your program requires file processing,…such as reading a series of records and then creating…a report, it is important to make sure that you read…every record in the file. To get the entire file converted into one XML document, you could read each record into the COBOL program record description, then use the new XML GENERATE FROM statement to create.
