The very first program I ever wrote for pay--when I graduated from street 
walking to hall walking--contained a huge number of full-word counters. It was, 
if I may say, a superb program, but a colleague wondered why I needed three 
base registers. Turns out that my computer-school assembler class had never got 
around to GETMAIN and DSECTs. All my thousands of counters were coded as DC 
F'0'. (I was later told that my program was used by sysprog staff to benchmark 
new CPUs!)

Now of course I write large or necessarily reentrant programs with 'deferred 
load' of 'working storage' areas. How smart I is now.

Subject: (External):Re: How are Program Object sections with Defer attribute 
loaded?

It appears to me that deferred-load sections are merely an enhanced external 
dummy section (aka pseudo-register) facility.  The binder updates Q-cons for 
them, and it's up to the program to implement the actual in-memory version, and 
provide a method for finding it.  LE and its HLL ancestors have always done 
that.
