Inline print a sequence or strip '"'

[matthesoundman]

Hello,

I am trying to create a single string line from a large sequence. Is there a 
simple way to inline the sequence for writing to a file that doesn't include 
the seq structure and double quotes?

I tried: 
    
    
    let someHeaderRow = fmt"SN,ID,{someSeq}"
    writeLine(myFile, someHeaderRow)
    
    
    Run

When I write this line to a file it includes 
    
    
    "SN,ID,@["Item1", "Item2"]"
    
    Run

in the corresponding line written.

I don't want the characters @, [, ], and ". I tried to just strip them out, but 
I cannot figure out how to strip " character.

Any help or tips would be greatly appreciated.

Thank you kindly.
