Thanks for the reply macropod.

I believe I did see all lines being replaced with FTEST(global.test_1). The breaks you're talking about must have been causing issues before.

For the attachment, the second command appears to have worked! However, the first string seems to not have changed. What I have now is:

global.test_1 = 1\2\3\sample_1.xxx
FTEST(global.test_2)
FTEST(global.test_3)

This was done in the attachment. Is there any reason why the first line remains unchanged?

Thanks.
