Oi,

Tenho um problema encalhado aqui: uma DLL, feita em Fortran (Compaq
Visual Fortran), e que era chamada originalmente dentro do Excel com
VBA, e estou mudando o sistema do Excel para o Delphi 7.

Para alguns dados, j  roda igual nos dois, mas para outros, d  o
seguinte erro:

---------------------------
Debugger Exception Notification
---------------------------
Project SisOpt.exe raised exception class EInvalidOp with message
'Invalid floating point operation'. Process stopped. Use Step or Run
to continue.
---------------------------

Esse erro ocorre durante a execu‡Æo da DLL, ela roda uma parte (faz
alguns c lculos, gera arquivos, chama um outro prg externo para
processar eles, ele roda e completa normal, mas depois disso a DLL
aborta com o erro) S¢ ocorre quando chamado pelo Delphi, no Excel/
VBA roda ok at‚ o fim.

J  tentei mapear os valores de todas as +200mil vari veis passadas
para a dll achando que algum estivesse trocado mas todos sÆo iguais.

Inclusive um outro erro que dava no inicio foi corrigido, array[i,j]
tem a aloca‡Æo invertida na mem¢ria (do Delphi em rela‡Æo ao VBA ou
Fortran) e precisou indicar como array[j,i].

Algu‚m tem id‚ia do que pode causar esse erro e como corrigir?

Abaixo estÆo as declara‡äes da rotina, tipos e chamada no VBA e no
Delphi:
