#152 Vector indices not working correctly
Hi,
I am trying BLT with Tcl 8.6 and have found that the following expression is broken (or at least changed since BLT2.4z)
[test12 1:14] ~> tclsh8.6
tclsh8.6 [/local0~] package require BLT
3.0
tclsh8.6 [/local0~] blt::vector create foo
::foo
tclsh8.6 [/local0~] foo append [list 1 2 3 4 5 6 7 8 9 10]
tclsh8.6 [/local0~] blt::vector expr foo(2)
3.0 4.0 5.0 6.0 7.0 8.0 9.0 10.0 -2.4983353906949635e-127 -2.4983353906949635e-127
tclsh8.6 [/local0~] blt::vector expr foo(2:2)
3.0 4.0 5.0 6.0 7.0 8.0 9.0 10.0 -2.4983353906949635e-127 -2.4983353906949635e-127
tclsh8.6 [/local0~] blt::vector expr foo(2:3)
3.0 4.0 5.0 6.0 7.0 8.0 9.0 10.0 -2.4983353906949635e-127 -2.4983353906949635e-127
tclsh8.6 [/local0~] blt::vector expr foo(end)
10.0 -2.4983353906949635e-127 -2.4983353906949635e-127 -2.4983353906949635e-127 -2.4983353906949635e-127 -2.4983353906949635e-127 -2.4983353906949635e-127 -2.4983353906949635e-127 -2.4983353906949635e-127 -2.4983353906949635e-127

I've committed a change to fix this. The vector duplication routine had the wrong length (it was using the length of the entire vector instead of the range). So it was grabbing values beyond the end of the vector.
[What's weird is that your example ran correctly with Tcl8.5.]
If you are still seeing this problem or any other, please let me know.
Thank for the bug report. I really appreciate it.

Lovely, thanks!
I have a few other bugs - I'll report them as well.
