Re: [Pharo-users] question on syntax negate numbers

3 @ - space 5 is what I object to (and Opal allows) with this i have no problems, it follows simple obvious rules as long as one knows that #@ cant be an unary operator. is 4 - 5 two literals, or is it two literals separated by the - operator ? but then there is no situation in which the -

Re: [Pharo-users] question on syntax negate numbers

dont know but g let me try yet another attempt at rephrasing this. suppose you ask an intermediate beginner how 5--4 would be parsed, as: a) 5 - -4 b) 5 -- 4 perhaps he does not need to look up the chapter in the pharobook and will choose b). but if he looks into the pharobook he will read under

Re: [Pharo-users] the simplest program of the world

Hi Hans, i guess you are asking for a way to make a batch file that when double-clicked immediately starts your program? a batch file with something like this: ~/pharo3.0/bin/pharo ~/pharo3.0/shared/yourImage.image ~/pharo3.0/shared/start.st would do that. start.sh should be a text file with

Re: [Pharo-users] Glamour question
