It supports the substring with positive and negative vals so:
${foo:3:4} would start at char 3 in the string and eval to the next 4 chars ${foo:-3:2} would start at the end and go back 3 chars then print the next 2 chars
If the var name is followed by a ( or a space, it will pass the values to the FSAPI and expand the result inline.
${sofia_contact 1004}
equiv of...
${sofia_contact(1004)}

Hi. I was experimenting with ${variable} and was wondering what could be in there before the }? I can do a substring if I say variable:2, but I wonder what else you can do? The bash manual has all kinds of things you can have, but how much of this will fs do?
Thanks in advance for any suggestions.
