.set symbol, expression
Set the value of symbol to expression. This changes symbol’s value and type to conform to expression. If symbol was flagged as external, it remains flagged (see Symbol Attributes).
.set a symbol many times in the same assembly provided that the
values given to the symbol are constants. Values that are based on expressions
involving other symbols are allowed, but some targets may restrict this to only
being done once per assembly. This is because those targets do not set the
addresses of symbols at assembly time, but rather delay the assignment until a
final link is performed. This allows the linker a chance to change the code in
the files, changing the location of, and the relative distance between, various

file is the last value stored into it.

‘symbol defl expression’ instead.
