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. . .

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. sas On Thu, May 11, 2017 at 7:59 AM, Peter Relson <[email protected]> wrote: > >How does one request that "deferred load" section be loaded now? > > "One" does not.
