But what do nested arrays buy the average >APL user? Besides 3 character string arguments to functions, I mean. "Array of strings" is a natural concept which has no clean representation in standard APL. (Padding a 2D array destroys the significance of trailing blanks, and may use an unacceptable amount of space.) A function with three string arguments is a special case of this. Also, it's often useful to mix numeric and character data in the one object (like "struct" in C). This is a heterogeneous array rather than a nested array, but some implementations handle both with the same language features. Karl W. Z. Heuer (ihnp4!bentley!kwh), The Walking Lint
