How to put a program to sleep

The environment is Visual COBOL 2017 and the objective is to put a program into sleep mode for one minute. Looking in the COBOL manual there is a System Routine of CBL GC NANOSLEEP that will do the job but the call to this routine fails (not found). Searching my C drive does not find the routine. So my questions are;

1. Is this routine the way to go or are there other alternatives? 

2.  If this is the alternative, how do I acquire this System Routine?
