I think that block arguments are like method arguments and are read only. Now I do not remember.

Re: [Pharo-users] PlotMorph on Pharo 6.1

I do not get what you mean. Stefan fixed the problem so may be there is a problem on 64 bits. I have no idea. So far he fixes the previous problem. So let us fix the new one. But so far I cannot reproduce it.

Hi mark live is chaotic here with two or three meetings in parallel, visitors, and a lecture to finish Now I tested. I took a Pharo 6.1 32 bits and loaded PlotMorph from the catalog It load Stefaneggermont.8 Can you tell us how to reproduce your problem?

Thanks We can start to use https://github.com/SquareBracketAssociates/PharoInProgress/blob/master/ST99… the idea was that a guy wanted to have a lot of small exercises.

Re: [Pharo-users] Writing XML

by Jimmie Houchin

Thanks. I am trying to learn the ways of Pharo 6 and not use StandardFileStream and MultiByteFileStream. So I do not know all of the best ways to do things. Thanks for the education. Your "best" way worked perfectly in Pharo 6. Again, thanks. Jimmie On 09/14/2017 07:24 AM, Henrik Sperre Johansen wrote: > Jimmie Houchin-5 wrote >> I still do not know how to do this correctly.

Because it is not so easy to determine what Pharo7 image version to actually try, I noticed that there is at least one 6521 image that is tried to be opened with a newer (32 bit) vm. Stephan
