To efficiently check the "populated size" of an array, you could use #ifdef in a
binary search manner:

#local iLastKnownPopulated = -1;
#local iFirstKnownUnpopulated = dimension_size(MyArray,1);
#while (iLastKnownPopulated + 1 < iFirstKnownUnpopulated)
  #local iMid = int((iLastKnownPopulated + iFirstKnownUnpopulated)/2);
  #ifdef(MyArray[iCenter])
    #local iLastKnownPopulated = iMid;
  #else
    #local iFirstKnownUnpopulated = iMid;
  #end
#end
#local PopulatedArraySize = iFirstKnownUnpopulated;

(untested draft)
