For a better understanding of debugging parallel segments of an application I have generated the 'openmp_samples'
Running with: Microsoft Visual Studio Professional 2015 Version 14.0.25420.01 Update 3
and
Intel® Parallel Studio XE 2016 Update 4 Composer Edition for Fortran Windows* Integration for Microsoft Visual Studio* 2015, Version 16.0.0063.14,
Executing the application in debugging mode some variables are not visible. For example using QuickWatch fortran variables 'start' and 'end' are 'undefined variables'.
