I do a lot of sub-routine looping programing using similar to this  

>#2501:#71=2501;goto#71

<#71: if(#71>2499)and (#71<2599)then
{
 if@(#71)>0and ???then
 {
   ?????????
    #8=@(#71-100)/@#71+300)
  }
};goto@(#71+100)

My fields are all numbered very orderly and it allows me to do much subroutine and line and column programing from a subroutine using the @field# command

1.   Should I consider naming my fields the old programing numbers so I don't loose this ability?

2.   If I do Will Sesame handle it properly?
 
Oh I see Sesame does not let you start a field name with a number.   I could put a null character at the beginning of each number and then delete the null character off in programing
