Keywords: Pyramid, f77, unexplainable compiler error


 I have a Fortran program that I am trying to compile on a 
 Pyramid dualPort 0s4.0 machine.  I am getting a message:

 Compiler error: Assign_T_Reg - expression too complicated

 from f77.  I have isolated the fault to a section that
 begins with an if(blahblahblah) go to xxxx
 where xxxx is about 80 code lines later.
 This is in a Subroutine, if I delete the Subroutine
 statement and the returns (make it into a Main)
 it compiles just fine.  If I delete 6 or eight of the
 code lines between the go to and it's target, it will
 fly.  Can anyone shed some light on this limitation
 of the Pyramid f77 compiler?
