Going by that standard I was at least a Great Programmer:
"No, your Real Programmer uses OS/370. A good programmer can
find and understand the description of the IJK305I error he just
got in his JCL manual. A great programmer can write JCL without
referring to the manual at all. A truly outstanding programmer
can find bugs buried in a 6 megabyte core dump without using a
hex calculator. (I have actually seen this done.)"
Not that there is an IJK305I error, but I used to know at least
a few dozen of those codes off by heart and knew where int he
shelfloads of manuals to look for the rest. And I could
certainly write JCL (and wrote programs to write JCL). I
occasionally found errors in hex dumps without benefit of
calculator as well, but only in VM (or occasionally MVS) control
blocks and with the help of the data structure manuals.
A colleague of mine could both do hex arithmetic in his head and
read 360/370 machine code from dumps and at least once confused
the people who took problem calls at IBM by telling them exactly
what the programmers had done wrong in the source code of a
program for which we didn't have the source code - the error was
produced by an obvious typo in the assembler. Obvious to him
that is. Not me.
