Simple Variables

Simple variables in Zephyr hold basic values. There are three types:

  • PT: Printable Text (strings of characters)
  • INT: Integer (whole numbers)
  • FLOAT: Floating-point number (decimal values)

PT (Printable Text)

Represents a sequence of characters.

  • usage: 
    myText # PT:HelloWorld!~|0;
  • Parameters:
  • |~0 → Marks the variable as non-constant (default).
  • |~1 → Marks the variable as constant (value cannot change).

INT (Integer)

Represents whole numbers without decimals. - usage: 

myText # INT:123;
- Valid Values: Positive or negative whole numbers (e.g., 0, 42, -99).

FLOAT (Floating-point Number)

Represents decimal values. - usage: 

myText # FLOAT:3.1415;
- Valid Values: Positive or negative numbers with decimals (e.g., 0.0, -1.25, 99.999).

Modifying Values

To modify variables, use the ? w: operation.

usage: 

<VariableName> ? w:<Value>;
<VariableName> ? w:'<AnotherVariableName>';
Parameters: - <VariableName> → Name of the variable you want to modify. - VariableName → Must match the variable’s type. - 'AnotherVariableName' → By entering any variable name inside ' ', its current value is copied.

Example: 

a # INT:10;
b # INT:0;

b ? w:'a';   ~ b now holds the value of a → 10

Incrementing:

  • Increment integer or float by 1 (or 1.0):: 
    counter ? w:++;
  • Decrement integer or Float by 1 (or 1.0): 
    counter ? w:--;
  • Increment PT: 
    printableText # PT:HelloWorld;
printableText ? w:++;
    printableText after increment: HelloWorldHelloWorld
