Follow-up Comment #9, bug #51871 (project octave):
A couple discussion points.
1) As far as 'na'/'Na'/'nA' vs. 'NA', why accept lower case letters if Octave
doesn't accept them at the command line, e.g.,
octave:9> x = [na, 1, pi]
error: 'na' undefined near line 1 column 6
2) The help for 'load' states
'-ascii'
Force Octave to assume the file contains columns of numbers in
text format without any header or other information. Data in
the file will be loaded as a single numeric matrix with the
name of the variable derived from the name of the file.
which doesn't mention any elaborate handling of comment lines, etc. The
documentation and actual internal programming should match more closely
whatever the behavior is.
