They are equivalent to plain c "arrays" where indexing involves calculating the offsets f2c style (almost trivial to accomplish with macro). Translate 0 Kudos Copy link Reply jimdempseyatthecove Honored Contributor III 06-05-2018 06:49 AM 1,351 Views On the C/C...
now whats the best way of array indexing them into a doubly linked list. im assuming ill need 3 arrays, and index/next/ and prev. any hints? Upvote 0 Downvote Jan 28, 2010 Thread starter #14 Mercfh Programmer Oct 26, 2009 13 US crap modula didnt work this code does work using...

In the following code example, you see the main computational kernel that updates the temperature on a 2D grid of points. It usesDO CONCURRENTloops to step through the 2D iteration space using the combined indexing capability ofDO CONCURRENTas described earlier. This expresses more parallelism and...
