I have investigated a bit further

I now have 5 subroutines in which the first variable in the DATA
statement has value 1.0Dn where n is positive or zero that are
assigned value 0.0D0 rather than 1.0 or 100.0 or whatever.

I have a case of the first one in the list being 1.0D-2 and several of
it being e.g. 6.28...D0 or 0.0001D0 and getting the correct value.

Lots of aips programs are affected.
