Title: #case how to end or better yet how to end blocks in general
Post by: kryton9 on June 19, 2011, 08:31:12 PM

In the help it states:  #case has block scope and reverts to its previous state when the block ends.

How do you end a block?

All functions,subs and methods, and control structures are blocks. Any entity defined within these is invisible to the outside. You can also define a scope explicitly.

Code: [Select]

scope(
....
...
)

The work 'block' may also be used. Or even a left bracket on its own.

I found #case capital to be most useful. Capitalised equates and types seem to be common practice in C,  to distinguish from other entities of the same name.

A simple example. This is cool Charles, I like it :)

Code: OxygenBasic

1. scope(
2. #case capital
3.         int I = 17
4.         int i = 76
5.  
6.         print "I    " I   '17
7.         print "i    " i   '76
8.  
9.         int NUMBER = 8943
10.         int Number = 25
11.         int number = 42
12.  
13.         print "NUMBER    " NUMBER   '8943
14.         print "Number    " Number   '42
15.         print "number    " number   '42
16. )
17.  
18.  
19. scope(
20. #case insensitive
21.         int I = 17
22.         int i = 76
23.  
24.         print "I    " I   '76
25.         print "i    " i   '76
26.  
27.         int NUMBER = 8943
28.         int Number = 25
29.         int number = 42
30.  
31.         print "NUMBER    " NUMBER   '42
32.         print "Number    " Number   '42
33.         print "number    " number   '42
34. )
35.  
36. scope(
37. #case sensitive
38.         int I = 17
39.         int i = 76
40.  
41.         print "I    " I   '17
42.         print "i    " i   '76
43.  
44.         int NUMBER = 8943
45.         int Number = 25
46.         int number = 42
47.  
48.         print "NUMBER    " NUMBER   '8943
49.         print "Number    " Number   '25
50.         print "number    " number   '42
51. )
