Well  you could erase   the first character too  note that erase   modifies the string    m VirtualHostName erase 0  1   m VirtualHostName erase m VirtualHostName size   - 1     But in this case  a simpler way is to take a substring   m VirtualHostName   m VirtualHostName substr 1  m VirtualHostName size   - 2     Be careful to validate that the string actually has at least two characters in it first

My BASIC interpreter chops beginning and ending quotes with  str- gt pop back    str- gt erase str- gt begin       Of course  I always expect well-formed BASIC style strings  so I will abort with failed assert if not   assert str- gt front           amp  amp  str- gt back             Just my two cents
