| 4 | 1 | Per Amundsen | |
| 5 | Sets the value of local variable %var to the specified value. | ||
| 6 | |||
| 7 | 6 | Per Amundsen | Syntax can be either _var %var = value_ or _var %var value_. | 
| 8 | 5 | Per Amundsen | |
| 9 | 9 | Per Amundsen | Multiple variables can be set in one line using comma as separator, _var %var1 = value, %var2 = value2_. |

| 13 | 1 | Per Amundsen | *Switches* | 
| 14 | |||
| 15 | -s - Display variable assignment value. | ||
| 16 | -g - Creates a global variable instead. | ||
| 17 | -n - Treat the value as plain text, even if arithmetic operators are used. | ||
| 18 | 13 | Per Amundsen | -i - Initializes a variable only if it does not already exist as a local or global variable. | 
| 19 | -p - Permits value to be 2 literal double quotes and permits value to end with a single [[$chr]](32) space. Also enables -n switch behavior. | ||
| 20 | 1 | Per Amundsen | |
| 21 | *Parameters* | ||
| 22 | |||
| 23 | <%var> - The variable to set. | ||
| 24 | 11 | Per Amundsen | [[= ]value] - Value to set the variable to. (can be a single [[Arithmetic Operators|arithmetic expression]]) |
