I was going to say, no it's not possible, but actually here is one:
<hansl>
open denmark # just for tabula rasa
Off topic, but you can just use "clear" for tabula rasa.
function bundle heyho(bundle indata)
bundle output
matrix m = indata["m1"]
output["m1copied"] = m
return output
end function
bundle passit
loop 10
matrix mtemp = ones(2,2)
passit["m1"] = mtemp
getoutput = heyho(passit)
endloop
</hansl>
Thanks, Sven. I see what you're talking about. The mess-up in
the GUI icon view was specific to the case where the icon view
is shown automatically. I had that turned off and so was not
seeing the bad stuff; if you opened the icon view manually
after running a script everything was OK.
Anyway, I believe this is now fixed in CVS and snapshots.
Here's a script I used for testing:
<hansl>
function bundle bunfun (bundle argb)
print argb
bundle bcpy = argb
return bcpy
end function
clear
bundle bun0
bun0["x"] = 0
loop i=1..4 -q
bundle b_$i
b_$i["str"] = "$i"
bun0["x"] = i
bundle extra = bunfun(b_$i)
endloop
print bun0
</hansl>
