Question about Alasm 4.1

Hmm..what am I talking about?..Oh, yes!
Hello All!

I have a subject. The point is that while delving into the Alasm code, I found
certain commands (directives):
BIN, MACRO, ERASE, DISPEND, MEDUP, STOP, ELSE, INF, IF, ENDIF...
Who knows how to use this, because if you write MACRO in the label name
then when compiled, Alasm outputs something like this label
error #00 (like, invalid command). And the help for Alasm is apparently
old, from previous versions, but it is mentioned there that in the next
versions there will be support for macros, etc.
Maybe someone knows how this works and how to use it? ;-)
