The variable Tab is defined to be used instead of char(9)
Example (1):
see :one + nl + tab + :two + nl + tab + tab + :three
Output:
one
two
three
You can change the variable to another value
Example (2):
tab = " "
see :one + nl + tab + :two + nl + tab + tab + :three
Output:
one
two
three
5.15 Using CR as Carriage return
The next example count from 1 to 10 in the same line during 10 seconds
load "stdlibcore.ring"
for x = 1 to 10 see x sleep(1) see cr next
5.16 Using the ! operator as not
We have = and != in the Ring language
But for the logical operators we have and, or & not
Now we can use the ! operator as not
Example:
if ! false
see "True!" + nl
ok
Output
True!
5.17 Using && and || operators
In Ring we have the next keywords for the logical operations
5.14. Using Tab instead of char(9) 54

4. Ring Documentation, Release 1.7
• and
• or
• not
Now we have also the next operators
• &&
• ||
• !
Example:
if one() and two()
see "Test1 - Fail" + nl
else
see "Test1 - Pass" + nl
ok
if two() or one()
see "Test2 - Pass" + nl
else
see "Test2 - Fail" + nl
ok
if one() && two()
see "Test3 - Fail" + nl
else
see "Test3 - Pass" + nl
ok
if two() || one()
see "Test4 - Pass" + nl
else
see "Test4 - Fail" + nl
ok
func one return True
func two return False
Output:
Test1 - Pass
Test2 - Pass
Test3 - Pass
Test4 - Pass
5.18 Using ? to print expression then new line
It’s common to print new line after printing an expression, We can use the ? operator to do that!
Example:
? "Hello, World!"
for x = 1 to 10
5.18. Using ? to print expression then new line 55

5. Ring Documentation, Release 1.7
? x

6.5 Better Ring Notepad
1. Ring Notepad is updated to include some new styles and the Main File ToolBar
The idea of the Main File ToolBar is to determine the main file in the project When the project contains many source
code files
This way you can run the project ( Main File ) at any time while opening other files in the project without the need to
switch to the Main File to run the project.
To quickly use this feature
(Open the project main file)
Press Ctrl+Shift+M to set the current source code file as the main file
Open and modify other source code files in the project
To run the project (Main File) at any time press Ctrl+Shift+F5 (GUI) or Ctrl+Shift+D (Console)
