Yes. Also some names - x and y - though short have become meaningful through conventional use. Consequently screenX and screenY would normally be understood as screen coordinates, meaning that distanceFromTheLeftEdgeOfTheScreen and distanceDownFromTheTopOfTheScreen are (thankfully) not typical.

I think that by now they have become more natural than outer_loop_index middle_loop_index inner_loop_index although I suppose calling something a "loop index" is not fully informative... but taking as an example Warshall's algorithm (all pairs connectivity / shortest paths) for i = 1 to n for j = 1 to n for k = 1 to n do if (a[i,j] & a[j,k]) then a[i,k] = true; what would it make sense to call them? In this example case, they could be from_point_number, via_point_number, to_point_number ... but is that how we think of them, or do we think of them as "counting loop indices" ... in which case, perhaps we don't really think of them as variables in the normal sense, but part of a stereotypical syntactical construct? __John ---------------------------------------------------------------------- PPIG Discuss List ([email protected]) Discuss admin: http://limitlessmail.net/mailman/listinfo/discuss Announce admin: http://limitlessmail.net/mailman/listinfo/announce PPIG Discuss archive: http://www.mail-archive.com/discuss%40ppig.org/ ---------------------------------------------------------------------- PPIG Discuss List ([email protected]) Discuss admin: http://limitlessmail.net/mailman/listinfo/discuss Announce admin: http://limitlessmail.net/mailman/listinfo/announce PPIG Discuss archive: http://www.mail-archive.com/discuss%40ppig.org/
