Method get_program_array

core/src/vm/mod.rs:424–437

Returns the value of an element in the program-scope array variable `key` at the given `subscripts` as a `ConstantDatum`. Returns `Ok(None)` if the variable is not defined (no image is loaded or the variable was not declared). Returns `Err` if the variable exists but is a scalar (use `get_program` instead), or if the subscripts are out of bounds.

        &self,
        image: &Image,
        key: &SymbolKey,
        subscripts: &[i32],

    /// variable was not declared).  Returns `Err` if the variable exists but is a scalar
