Referencing FieldCodes in VBA

[ptmuldoon]

I'm trying to figure how to either reference or assign a variable to various filed codes like {AUTHOR}. How to do reference the { } brackets? I tried the CHR codes, but it didn't want to work. Any ideas?

Sub FCTest()
    Dim FC As String
    
    FC = "char(123) AUTHOR chr(125)"
    MsgBox FC
    

End Sub
