Are you *sure* there is no error message?
I got "error: load: failed to read matrix from file 'dynam'"
If I replace "D" with "e"  it works just fine.

There is no error message

that's maybe a bigger concern. how is it there are no error messages produced by Octave? What does your screen show after each line of input?

'load' expects a certain kind of data.  Using D as an exponential delimiter as Dmitri said does not work with 'load'. if you used 'dynam = dlmread('dynam')', that line would work because dlmread is better at deciphering files with delimited text data.

Thank you for the response
Once I changed from double precision in output print to single precision it plotted- So the D is not accepted in Octave while E-04 is

strange

dlmread is able to read that format without a problem.  Checking, matlab2021a is able to load('dynam') as well.  I don't see any particular reason load shouldn't be able to read it, so it may be worth a bug report.

correction, it appears dlmread ignores the D.  e.g., the last line in the file is:

12.00000  .511026D-02  .334856D-02  .101089D-03

read in by matlab as:
(format long)
12.000000000000000   0.005110260000000   0.003348560000000   0.000101089000000

but dlmread as:

1.200000000000000e+01   5.110260000000000e-01   3.348560000000000e-01   1.010890000000000e-01


so, this does seem to be a compatibility bug.

Thank you very much
Now I learned something new indeed
and have been too used to Matlab in this respect

12.000000000000000   0.005110260000000   0.003348560000000   0.000101089000000

but dlmread as:

1.200000000000000e+01   5.110260000000000e-01   3.348560000000000e-01   1.010890000000000e-01


so, this does seem to be a compatibility bug.
