Re: Simple Program Won't Run

[Gary Highberger]

Hi Help-Smalltalk,

I put periods after each line and then the Smalltalk program ran just fine.
Is there a way to avoid having to put periods after each line? What end of
statement characters besides period does Smalltalk expect? Maybe my editor
can be reconfigured accordingly.

Thanks everyone,
Gary
