> Hi Guys,
Thanks very much for your solutions.
Craig's and Martin's are best suited or my app, especially as it's
on OpenVMS using v5.4, at which OpenVMS is forever stuck.
Dick's idea of v5.5 having a DIM parameter is excellent & almost
certainly functional once you get your 5.5 CD's for Windows & *nix.
And Paul's way off in left field with F90 - I'm cosy with F77, thanks ;-)
