Translator – Find Code (New Design)

The current find code routine pops all of the operands for an operator or internal function from the done stack, checks the data type of each changing the code to an associated code as needed, and inserts hidden conversion codes as needed.  The find code routine is currently called from these locations:

add operator – to get the appropriate code for unary and binary operators
add print code – to get the data type specific print code
set assign command – to get the data type specific assignment code
close parentheses handler – to check the arguments for internal functions

The Translator will be modified to find the appropriate binary operator code at the first operand, and find the appropriate binary operator code again at the second operand. Also for internal functions, each argument will be checked as it is processed, in other words, in the comma handler.

The new find code will only check one operand where the index of the operand to check will be passed as an argument. The callers of find code will be modified:

operator handler – call for first operand of a binary operator
add operator – call for second operand of a binary (or operand of a unary) operator
comma handler – call for current argument of an internal function
close parentheses handler – call for current argument of an internal function
