Something to watch out for in PI flavour ... Even if your array is two-dimensional, there's only one element 0. The other thing to watch out for (and a good case for using Prime-style arrays) is if you only want to use the first few fields of a record. When using MATREAD (and friends), if you don't provide enough elements, Pick-style gives you an FM-delimited dynamic array in the *last* static element of your array. Prime-style uses element 0 to store the excess elements. Which is why, if you overflow a dimensioned array, PI-style returns 0 as the number of elements read, because it's the index of the last element filled! A program I wrote blew up because somebody else didn't bother to read my copious warnings that if you fed my routine dud data, it would misbehave ... :-( they didn't specify max-elements properly :-( So Pick-style, if you only have ten elements, you really need to declare your array as 11, or you could have a nasty shock if a record does acquire an 11th element ...
