 Posted: Sat Jul 26, 2014 6:35 pm Post subject: When do I put "return 0"? |
 |
|
For example:
| Code: | proc give {nick host hand chan arg} {
global givechan
if {$chan eq $::givechan} {
puthelp "PRIVMSG $givechan :Here is $arg for you"
}
return 0
} |
VS.
| Code: | proc give {nick host hand chan arg} {
global givechan
if {$chan eq $::givechan} {
puthelp "PRIVMSG $givechan :Here is $arg for you"
return 0
}
} |
VS.
| Code: | proc give {nick host hand chan arg} {
global givechan
if {$chan eq $::givechan} {
puthelp "PRIVMSG $givechan :Here is $arg for you"
return 0
}
return 0
} |
etc.
Where is/are the proper place(s) to put a "return 0"? |

Firstly, you have to understand that by declaring the global variable within the procedure, you do not then need to use the global variable in the manner you're calling it.
For example
| Code: |
global givechan
if {$chan eq $::givechan} {
|
You had already declared global givechan. This means that you just have to do
| Code: |
if {$chan eq $givechan} {
|
If you do NOT declare the 'global variable' in the proc, then you would use the $::method
Secondly, for return, check this out. It can be a bit confusing, but a lot of the time it's best to just test it yourself, being on partyline with debug. If you add debugging code, it makes it even better so you can see everything that's going on when triggered.

That could depend on what you want to happen.
You'll get a better feel for it, if as Get_A_Fix suggested, you experiment with it.
In addition the the page that he gave you to read, here's some more good info on the subject, found here:

I hope this helps. |
