COBOL 2023 introduced the <code>AFTER</code> phrase of the <code>CONTINUE</code> statement to specify a time period in seconds for which execution will be suspended, which, depending on implementation, could be not an integer.
There are two methods for putting the program to sleep, both requiring unofficial extensions.▼
