Our program demonstrates the concept of handling multiple concurrent operations. In COBOL, we don’t have direct equivalents to Go’s channels and select statement, but we can simulate similar behavior using file handling and timed waits.
In this COBOL example, we simulate concurrent operations by writing to two separate files with a delay between writes. Then, we repeatedly check these files for new content, simulating the behavior of selecting from multiple channels.
To run the program, compile it with a COBOL compiler and execute the resulting binary.
Note that the execution time will be approximately 2 seconds, simulating the concurrent operations in the original Go example. The COBOL version uses file I/O and timed waits to achieve a similar effect to Go’s goroutines and channels.
This example demonstrates how to handle multiple concurrent operations in COBOL, even though the language doesn’t have built-in constructs for concurrency like Go does. We’ve used file handling and timed waits to simulate similar behavior.
