Konsol

The Konsol: module handles terminal I/O, process control, and utility conversions. Konsol:Print is single-argument — use + or ${} to combine values.

Call	Effect
`Konsol:Print(expr)`	Print one expression, then newline
`Konsol:Message(expr)`	Alias for Print
`Konsol:Log(expr)`	Print with `[LOG]` prefix
`Konsol:Input(varName)`	Read a line from stdin into `varName`
`Konsol:Input("prompt", varName)`	Print prompt then read
`Konsol:Exit()`	Exit with code 0
`Konsol:Exit(code)`	Exit with given code
`Konsol:Chr(n, outVar)` / `Konsol:Char(n, outVar)`	ASCII char for code `n` → `outVar`
`Konsol:Asc(str, outVar)` / `Konsol:Ascii(str, outVar)`	ASCII code of first char of `str` → `outVar`
`Konsol:IsNumeric(expr, outVar)`	`true` if value is a valid number → `outVar`
`Konsol:Delay(ms)`	Sleep for `ms` milliseconds
`Konsol:Run(cmd, outVar)`	Run shell command, capture stdout → `outVar`

Konsol:Input stores a Number if the input looks like one, otherwise a String.

Passing more than one argument to Print, Message, or Log is a syntax error.

Konsol:Print("Hello, world!");

Var:String name;
Konsol:Input("Enter your name: ", name);
Konsol:Print("Hello, " + name);

Var:Number code;
Konsol:Asc("A", code);
Konsol:Print(code);         // 65

Var:String ch;
Konsol:Chr(65, ch);
Konsol:Print(ch);           // A

Var:Boolean isNum;
Konsol:IsNumeric("42", isNum);
Konsol:Print(isNum);        // true

Var:String output;
Konsol:Run("echo hello", output);
Konsol:Print(output);       // hello
