Hi Greg,

I would imagine that the difference is in the implementation of the
shell that you are using.  I see differences using 'sh' on Linux
since it is actually 'bash'.

Why do you have two shifted quotes?  The ZA syntax in McIDAS is:

ZA color height justify <keywords> "text

Note the single shifted quote mark.

> this line in the script generates an error message:

Yup, the 'sh' scanner ('bash') is complaining about the second
shifted quote.

Remove the first shifted quote mark and then evaluate if you need
the tripple backslashes to escape the second one.

I am just heading out the door.  I won't be in touch until after 7 pm
tonight.


Cheers,

Tom
