hi all,

my code:
-----------------------------
.run
openw,lun,'zhut.txt',/get_lun,width=40
myi.field8=myi.field1+myi.field4
myi.field6=myi.field8(sort(myi.field8))
printf,myi.field6(uniq(myi.field6))
free_lun,lun
end
-----------------------------
and it turns out to

PRINTF: Expression must be a scalar or 1 element array in this
context: <STRING Array[41952]>.

but if i change printf to print, myi.field6(uniq(myi.field6)) will be
displayed on the screen.

what's the other difference btw print and printf?

thanks
sukye
