**Note**: On older versions of Windows you may need to set the `HKEY_CURRENT_USER\Console\VirtualTerminalLevel` registry key to `1` to activate [Console Virtual Terminal Sequences](https://learn.microsoft.com/en-us/windows/console/console-virtual-terminal-sequences?redirectedfrom=MSDN).

To print unicode to the command prompt on the Windows command prompt you may need to `chcp 65001`.
# 8-bit and 16-bit colours
A Simple API to print [ASCII escape codes](https://en.wikipedia.org/wiki/ANSI_escape_code).
```4d
var $CLI : cs.CLI
$CLI:=cs.CLI.new()
//foreground
$CLI.print("Hello World"; "red;bold;underline").LF()
//foreground and background
$CLI.print("Hello World"; "red;yellow;bold;underline").LF()
```
```4d
$CLI.LF()
//16-bit color
For ($i; 0; 255)
$CLI.print(String($i; "^^0"+" "); String($i)+";bold")
End for
$CLI.LF()
```
# Progress indicator
```4d
var $CLI : cs.CLI
$CLI:=cs.CLI.new()
$CLI.ES().XY(0; 0)
$CLI.hideCursor()
For ($i; 1; 100)
$CLI.CR().print(String($i; "^^0")+"%%").EL()
DELAY PROCESS(Current process; 1)
End for
$CLI.showCursor()
$CLI.LF()
```
# Notes
By default, diagnostic warnings (level 5) are printed to the console in headless mode. To filter these messages from the CLI, you might want to activate the diagnostic log file or else limit the information to errors (level 6).
* Settings/logConfig.json
```json
{
"diagnosticLogs":{
"state" : 1,
"level" : 6
}
}
```
