What about writing a small assembler routine to do the AMODE switch.
The routine would use an input value of say -1 for query, 0 for set to 24-
bit mode, 1 for set to 31-bit mode, and by extention, 2 to set to 64-bit
mode. The routine would return (either as a function call, or in a separate

The appends that refer to what we call directed load are the right
approach if you are APF-authorized.

Examine the directory entry and determine the length
Obtain storage of that length
LOAD with ADDR=.
Both the BLDL and LOAD would want to specify whatever DCB is appropriate,

I have written a called Assembler subroutine that performs a LOAD for a table

Instead of copying it, use IARVSERV to map it below the line.

1) The LSEXPAND macro instruction takes the form
| LSEXPAND normal=n,recovery=r
where
96 n = 16000,

the first time the macro is used and
n(i-1) n(i) = 16000,
r(i-1) r(i) = 4000
the i-th time, i 1, it is
