[Gretl-devel] Edge cases for "end" operator

Hi all, I wrote some unit-tests for the recent "end" operator. See here: https://sourceforge.net/p/gretl/workspace/ci/09881e0435c18730b1a8b54210dc... I found some edge cases for which the current behavior may be discussed: <hansl> clear set verbose off WHICH = 1 if WHICH == 1 bundles B = array(0) eval B[end] elif WHICH == 2 matrix m = {} eval m[end] elif WHICH == 3 strings Sempty = array() eval Sempty[end] elif WHICH == 4 open denmark.gdt --quiet --preserve list L0 = null eval L0[end] elif WHICH == 5 open denmark.gdt --quiet --preserve eval LRM[end] # Index value 2147483647 is out of bounds elif WHICH == 6 open denmark.gdt --quiet --preserve eval LRM[(end-1)] /* DUM_END: not interpreted for upsym SERIES The symbol 'end' is undefined Data error */ endif </hansl> For the first four cases, I get the message (by the way, no error or warning is flagged): "Index value 0 is out of bounds". Is this expected, or should it be handled differently? For case 5, I would have expected the last entry (conditional on the currently active sample) of series LRM. Hope that's useful. Best, Artur
