The let statement assigns the value of an expression to a variable.
{let} var = exp
| var | Variable that is assigned the value of exp. Can be a simple variable, an array element, an extraction, substring, or both extraction and substring. |
| exp | Value to be assigned to var. |
The let statement is a holdover from the original Dartmouth BASIC, and is only included for compatibility. It is supported to facilitate program readability.
let a = 5
The statement above is exactly the same as:
a = 5
