[scilab-Users] "error 240" issue while trying to open a file

[thomas.auphan at free.fr]

Thank you Jacco,
Using the full path seems to be the solution (on Linux and on Window).
(I'm a bit surprised, because I think that I had tested this idea before without
results ... but it currently works).

Thank you again,
Thomas AUPHAN
