Three main data structures used throughout the first pass of the assembler are given below:
- LOCCTR i.e. Location counter
- OPTAB i.e. operation code table
- SYMTAB i.e. Symbol table
LOCCTR: It is Location Counter that maintains track machine addresses of symbolic tables.
OPTAB: In this operation table mnemonic operation code and have its machine language equivalent.
OPTAB can be implemented by using hashing function for fast access.
SYMTAB: in Symbol table symbolic label, operand and their consequent machine are keeps addresses.
a. For symbolic label, fill in address and symbol (as per to current LOCCTR).
b. For symbolic operand, fill into symbol and mark this as undefined. Address field will be challenged later.
