Level-49 is a special data item level in COBOL that is reserved explicitly for defining condition names. A condition name is a symbolic representation of a particular condition or state of a data item. It is associated with a particular data item and can be used in conditional expressions, such as IF statements and EVALUATE statements, to control the flow of the program based on the condition’s status.
The first step to programming on mainframes is to learn the programming languages that are commonly used, such as COBOL and PL/I. These languages are designed to work with the mainframe environment and will be required to write, test, and run programs on the mainframe.
