all very well, except that the API that most people use to
compile MI programs (QPRCRTPG) doesn't know about
Frank Soltis's book.  :-(

From Chapter 4 (The Tehnology-Independent Machine Interface)
of Frank Solti's excellent book "Inside the AS/400":

"The operand field, which is used to index into the ODV, was originally
16 bits long in the System/38, but the field was later expanded to 24 bits.
This means that a program can have up to 16 million (2^24) different
operands, and even that number can be extended."

ODT (Object Definition Table) consists of ODV (ODT Direction Vector) and
OES (ODT Entry String)
