Finally, section 7.3 describes methods for saving all the identifiers to be found in a Pascal source program in a symbol table. This both reduces the total

Once the grammar of a language is formally defined there are various algorithms which can be used to parse programs written in the language. The recursive descent method use

The declaratives comprise definitions, of types and constants, and declarations, of labels, variables, procedures and functions. It is unnecessary, in a Pascal com

For convenience, the compiled code is presented in assembly language form, rather than pure binary instructions. Standard assembly language conventions are used wherever possible, but the reader is warned that
