INPUT Execution Codes - Assigning

The assigning of the input values must be done separately from the parsing of the values entered due to the two input rules. For the example, this is steps 7 through 11. Some of these steps are standard expression codes: push a reference to an integer variable (step 7), push a value to an integer variable (step 9), and calculating a reference to an array element by popping a integer subscript value and pushing the reference to the element (step 11).

There will be a code to assign an input value to an input variable for each data type: InputAssignInt, InputAssignDbl and InputAssignStr. For InputAssignStr, the InputParseStr will created a string from the input value. This string will be assigned to the string variable replacing the previous string value, which will be deleted. Therefore, there will be no need to deal with temporary strings.

The values being assigned will need to stored temporarily somewhere other than the evaluation stack.
