code compaction vs readability is a long debated topic and end up being
developer taste specific. I personally prefer compaction too, but wanted to
respect the model I followed to favor consistancy over my personal taste. see
the code I refer too:
for (Lng32 i = 0; i < colNameLen; i++)
{
colName[i] = currPtr[currPos];
currPos++;
}
