Hello group, BASIC to Euphoria convert here. My main reason for learning to program is that I'm going into EE (that's elec. eng.) at Auburn this fall, so I've taught myself BASIC and now I'm moving on to Euphoria. The only thing that bothers me about Euphoria is when you call procedures, you have to use parentheses. I know this is traditional with programming languages... but it could be just as interpretable and just as readable without them, right? Of course you still could use parentheses, otherwise all previous code would have to be modified. Just like spaces and blank lines, programmers have their own style, so choice of parentheses around parameters could be another choice. Consider this: puts(1,"Ye olde way\n") puts 1, "The new way\n" --or-- key = gets (0) key = gets 0 --New way Like I said before, this is radical and goes against traditional style, but after all, isn't that what makes Euphoria so useful?

Completely unuseful Derek. Because Euphoria doesn't have an end_of_statement delimiter (like C and Pascal ';'), the parenthesis are required so the interpreter doesn't confuse missing parameters from other statements. Example: procedure myproc(integer i, integer ii) ... end procedure myproc 10 i = gets 0 Should mean: myproc(10, i = gets(0)) But also might mean that you forgot a parameter and wanted to code: myproc(10, ?) i = gets(0) Very different! That would be a hard to catch bug with your proposed syntax; a very error prone syntax indeed. Regards, Daniel Berstein [daber at pair.com]
