The early users of FORTRAN were perforce proficient assembly-language 
programmers.  The notion that statements in what I prefer to call 
statement-level procedural languages--They are not always higher-level 
ones--were, in effect, macros was obvious to them, so obvious that it often but 
not always went unsaid.
 
This had its down side.  Since these SLPL statements were like macros, it was 
not so obvious as it should have been that SLPLs needed their own, superimposed 
macro facilities too.  These facilities were long in coming; and all of them 
are still inadequate, even toy-like.  (The best of them, that of PL/I, provides 
almost no access tyo symbol-table information.)
