Change "" to '' for compatibility with linux

[paolomassa]

There are some places in the code in which strings are defined within "" (see, e.g., here and ). This is incompatible with linux distributions. It should be changed to ' ' in the entire software.

@paolomassa has any progress been made on this? Are you sure the issue is the 's or the encoding of the source files?

[paolomassa]

We still need to implement the modifications, I'll do that soon. For what I know it should be just a problem of changing " with ' , nothing more.

Ok I guess I just don't understand the problem "linux" doesn't have an issue with " or ' so it must be IDL on linux and even then I don't really understand. I have had encoding issues before ascii / utf-8 / utf-16 or latin1 etc

I created these tiny test scripts and they work on linux?

test_func.pro

function test_func

a = 'a'
b = "b"

print, a , b

end

test_pro.pro

pro test_pro

a='a'
b="b"

print, a, b

end

IDL> test_func()
ab
       0
IDL> test_pro
ab
``

For what I understood, the problem is that the IDL installation on linux has troubles sometimes when strings are defined within ". If I remember correctly, @PaipaPsyche reported this issue to me.

@PaipaPsyche could you please tell us more if it was you who found this issue? Thanks!

I'm running SSW on an Ubuntu distribution. For some reason I always have an error when running the demo because of these "" strings (the subroutines cannot recognize the specified date/UID ). The error disappears when replacing the " for ' in the scripts.

Do you happen to know the encoding of the file is?

[PaipaPsyche]

it's ASCII
