Hi Ed, > Your test program on unidata 7.1 takes 1137 milliseconds > - 1.1 seconds. Whilst this is not a totally valid comparison since your test was done on different hardware (mine was on my laptop), it does show that Unidata almost certainly cannot be using contiguous strings as it would take longer than this to copy the data. I have been intrigued by some of the Unidata performance figures I have obtained in the past where some things that should take a long time are actually very fast while sometimes the opposite is true. I am left wondering if there are some clever optimisations being done in the compiler. Perhaps someone from the development group will let a few secrets out.
