* Checks to see if the instructions are legal in the current assembly mode.
    * Allocates space for instructions and storage areas you request.

I need the source code for single pass assembler implemented in c

Answer 3

Generate their object code in memory for immediate execution –
load-and-go assembler
External storage for the intermediate file between two passes is
slow or is inconvenient to use
A one pass assembler passes over the source file exactly once, in the same pass collecting the labels, resolving future references and doing the actual assembly. The difficult part is to resolve future label references and assemble code in one pass.
