Fred,
Please give us a NOT operator... I miss doing...
Is there a spring feature for the StatusBar? Example...
would maximize the field according to the remainder window width
Any chance to have C like math syntax?

Hello,
First and 3rd requests are only syntax matter.
You can do:
And i've tested that the 0 comparing is as fast as ASM
And for the 3rd req, you can do a+10 instead a+=10, and b+1 instead b++
I'd prefer the syntax, power and flexibility of the C "for" loops as an alternative "for-next" loops syntax in PB, don't you?

hey thanks for the 3rd req tip...
yes i agree with you... however this is basic and for(a=0;a<10;a++) might create a hybrid language...

Well it seems that PB has smart reads... I remember if coding...
open some file handle = 0
repeat
a = readsomething(0) <- this will trigger run-time "input past end" error if the file is empty.
until eof(0)
close (0)
thanks for the tip

I use that snippet o code all the time when i need to read an entire file, never had a problem!

if the file is empty, then you might get a runtime error when using the Repeat loop... otherwise, it shouldn´t be a problem.. (as long as the file exists)

I second the not operator, yes is only about syntax but it will be hard to find a language that does not have it.
but please use a single letter otherwise there won't be much difference in typing
while !EOF()
wend

NOT is clearer when you are reading a listing.
While NOT Eof(1)
While ! Eof(1)
Sometimes I used to type | instead of ! in another language, then spend ages wondering why the code would not work. In some fonts the difference was only 1 pixel on the screen.

readability is all, it's simply easier to read:
if not eof(...)
if eof(...)
than it is
if eof(...)=0
if eof(...)<>0

You don't. Like Num3 said, I also use it that way and never get a runtime
error, even with 0-byte files.

And in good programming you should always check the file size, before opening it, no need to waste cpu when there's nothing to read:
Code: Select all
file.s="myfile.txt"
If FileSize(file)>0
If ReadFile(0,file)
Repeat
Debug ReadString()
Until Eof(0)
EndIf
EndIf

However, the only thing basic about purebasic is the word "basic" in the title
We already have a "hybrid" language, why not continue adding keywords?

Hmmm... How about some pointers to the Status Bar spring feature that wouuld resize itself to the width of the window...?
sigh!

Did some Pure Basic file coding these last few days... Still feels kinda naked without the NOT operator...
