How COBOL program is compiled?
COBOL compile procedure. An example shows a single-step procedure for compiling a source program. The JCL in Figure 1 executes the IGYWC procedure, which is a single-step procedure for compiling a source program. It produces an object deck that will be stored in the SYSLIN data set, as we can see in Figure 2.

How do I compile a mainframe program in COBOL?
To run your COBOL program in TSO, compile and link-edit the program, and then run it in either with or without ISPF. You must compile and link-edit your COBOL program before you can run it in TSO. After your COBOL program compiles successfully, you can run it with JCL without ISPF.
What is DB2 compiler?
The Db2 precompiler scans a program and copies all of the SQL statements and host variable information into a DBRM (database request module). The precompiler also returns source code that has been modified so that the SQL statements do not cause errors when you compile the program.
Is COBOL object-oriented language?

How do I compile and run a COBOL program in mainframe?
How do I compile a COBOL program in Unix?

COBOL is known as the Host Language. COBOL-DB2 applications are those applications that include both COBOL and DB2.
How can I run a COBOL program using JCL?
In order to execute a COBOL program in batch mode using JCL, the program needs to be compiled and a load module is created with all the sub-programs. The JCL uses the load module and not the actual program at the time of execution.
