If the syntax were truly ambiguous, HLASM's behavior would be
as unpredictable as METAL-C's. But perhaps it's undocumented.
And the assembler enforces no type checking:
FRED EQU *
...
LH R1,FRED
STH R1,JOE
...
L R1,FRED
ST R1,SAM
...
What's C supposed to do with JOE = FRED? (But how does
PL/S deal with it? Perhaps the DSECT conversion utility
should employ the PL/S rather than the HLASM part of
DSECT macros.)

Isn't much the same true for LE?
