How Chain operation copies the record's data to the input buffer for the program?

Question Posted / ravikumar


How Chain operation copies the record's data to the input buffer for the program?..

Answer / Deepak Kumar Gaur

Chain operation in RPG400 copies records from an external file into a program's input buffer, allowing the program to process those records one by one. The chain operation works by reading records from the external file and storing them sequentially in the program's input buffer.
