It might also be worth mentioning that as all variables (including
arrays) are strings, taking arr[x,n] could include dynamic array
delimiters. It follows that you will often want to limit the
extraction to a string from a single "atomic" field - as in arr<x,y>
[n,nn]. Put simply, you might be wise to code SUBSTRNG=STRNG<1,1>[1,4]
instead of SUBSTRNG=STRNG[1,4]. Have I clarified or confused?
