Having to partially dissect a 9000-line RPG-II program and came across a
file spec for a file that is an alternate index.  I'm really confused.  Does
IBM do some blackbox stuff for alt. indexes?  I know that they are logical
files.  The physical record is 320 bytes in length, but the logical record
is 334 and a DSPFFD list puts the two key fields defined for the alternate
index in 321-327 & 328-334.

Also, the RPG program's F-spec for this file shows the start position for
this key as 1 (does it matter for alt. indexes?)
