Re: Octave on Mac (Intel): GNUplot problem

[Stuart Edwards]

Thanks for your response.

Here's the first few lines of the script seshaft.m  .....

        #!/usr/local/bin/octave
        # A script ......
        #blah...
        #blah...

        #clear all the current variables

        clear all

        #get the name of a new file for this run

        filename = input("name of new run  ","s")

Trying to run the script from the directory where it resides ..

        SEsMacPro:seshaft stu$ ./seshaft.m

        <about 15 line feeds>

        ./seshaft.m: line 13: syntax error near unexpected token `('
        ./seshaft.m: line 13: `filename = input("name of new run  ","s")'


Checking the path to octave in the shebang line ..

        SEsMacPro:seshaft stu$ /usr/local/bin/octave
        GNU Octave, version 3.2.2
        etc
        etc

Manually starting the script from within octave ..

        octave-3.2.2:1> seshaft
        name of new run  testtest
        filename = testtest

So the parts seem to run independently but not together.

Adding: print -deps "plot.eps" doesn't seem to have any effect on the  
script when I run it 'manually'.

Thanks for your help.
