[Octave-bug-tracker] [bug #54622] test importdata fails in dev octave with windows

[Dan Sebald]

Follow-up Comment #57, bug #54622 (project octave):

@Rik: Ah, good catch.  I've updated the changeset, attached.  Checking against
EOF is correct, rather than std::isalpha (next_char)?  I mean, isalpha() is
going to be "locale-specific template" dependent as well, right?  It seems we
should avoid that too.

I was going to add a check to letters in the importdata.m file (i.e., change
one of the "Inf" to "Infj", but then I found the result odd with respect to
Octave command line input:


octave:8> A = [3.1 Infj NA; -Inf NaN 128];
error: 'Infj' undefined near line 1 column 11


The above suggests we can input "Infj" in a file, but not at the command
line.

Also, in the following:


octave:9> A = [3.1 Inf*j NA; -Inf NaN 128]
A =

     3.1000 +   0.0000i        NaN +      Infi         NA +   0.0000i
       -Inf +   0.0000i        NaN +   0.0000i   128.0000 +   0.0000i


how is the that first "Inf*j" acquiring a "NaN" in the real element of the
number?
