Answer / phil
All references to labels dependant upon the base registers
using statement below the DROP instruction in the listing
will be unresolvable by the assembler.

Answer / nsugandhi
It will give an error at the time of assembly, if there are
some labels defined in the program(provided they are being
referenced in your program). This is because the assembler
resolves the displacement of that variable from the location
where your base register is pointing to.

We cannot drop the base register, it is the memory location
for the whole program.
