Hi, This does NOT work ............ sequence found inside string include file.e include get.e sequence d atom w d=dir(current_dir()) printf(1,"%s\n",{d}) w=wait_key() yet this one does work !!! include file.e include get.e sequence d atom w d=dir(current_dir()) for i = 1 to length(d) do printf(1,"%s\n",d[i]) end for w=wait_key() what does .... sequence inside mean ??? OR where to look !!! I cannot find it. getting frustrated with simplicities !! OH WOE !! les.r.

That is, there are sequences inside sequences... for example: { 1, 2, "Sequence 1", 4, "Sequence 2", "etc." } printf()'s "%s" cannot output that kind of sequence. It expects "flat" sequences of integers only. printf(1, "%s", { "This is okay." } ) printf(1, "%s", { { "This is not.", "Because it has embedded sequences." } } ) > d=dir(current_dir()) > for i = 1 to length(d) do > printf(1,"%s\n",d[i]) > end for This works because you've sent a sequence element from d to printf(). The element d[i] always contains a flat sequence (or atom). > d=dir(current_dir()) > printf(1,"%s\n",{d}) This would work (but not as expected) if you wrote it as printf(1,"%s\n",d)

Hello les, sequence found inside string line 3 of myprog.ex This is a common error that I get all the time. To fix it. Go to that line and change d to d[1]. If you still get it change to d[1][1]. In other words puts(1,d) --dosen't work puts(1,d[1]) --dosen't work --keep doing this untill it works puts(1,d[1][1]-- works Once it does work and prints something you will see where your error is. Another example: sequence names names=("les","don","ccris"} puts(1,names}--sequence found inside string error puts(1,names[1]-- prints les Oh I see, I have to identify each element of the sequence with a number.
