Note 1308.0 DFVV unable to obtain array address in DEBUGGER 1 reply
CSC32::D_SANFORD 35 lines 21-MAY-1997 13:37
--------------------------------------------------------------------------------
Digital Fortran V6.4-165, OpenVMS VAX V6.2
When using the DEBUGger to show the address of an array on OpenVMS
VAX your given the address of the descriptor, on the Alpha you get
the address of the array.
Is there any easy way to get the address of the array on the VAX
without modifying the code? You can modify the code to use %LOC()
or an EQUIVALENCE statement, but the customer cannot modify the
code. The descriptor cannot be read either.
Regards, Drew Sanford
C970520-6054
integer a10(10), aa
equivalence (a10,aa)
a10(1)=1
print *, %loc(a10)
end
OpenVMS VAX DEBUG Version V6.2-000
%DEBUG-I-INITIAL, language is FORTRAN, module set to D$MAIN
DBG> sho sym/address a10
data D$MAIN\A10
descriptor address: 2243701
DBG> sho sym/address aa
data D$MAIN\AA
address: 512
DBG> ex 2243701
%DEBUG-E-NOACCESSR, no read access to address 00223C75
**************************************************************************
Steve Lionel asked us to use "DBG> EVAL/ADDRESS A10" and that gives
the address, but the customer was using "DBG> SHOW SYMBOL/ADDRESS *"
to get all the addresses displayed back, since EVAL does not support
wildcard this is not much use.
If you believe this is a bug, then it should be low priority as it
is only a inconvience.
