   I didn't mean to imply that it did.   
   As far as I remember, Fortran 77 does not allow it.   
   I never used later Fortrans.   
      
   I hadn't given the dynamic branch topic any thought until you raised it   
   and this was just me working through the things a compiler might have   
   to deal with.   
      
   I have written jump dispatch table code myself where the destinations   
   came from symbols external to the routine, but I had to switch to   
   inline assembler for this as MS C does not support goto variables,   
   and it was up to me to make sure the registers were all handled correctly.
