Offset function

[Robert Presender]

Using Rev 1.5A7.1 or Rev 1.1.1

With reference to transcript dictionary offset, I put example 3 into 
the message box with and without the quotes and obtained the same 
results.

offset("bark","embarking")
offset(bark,embarking)

Are the quotes necessary?  If necessary, under what conditions?

Thanks for any comments.

Regards ... Bob
