The executable obtained from compiling a fortran90 code gives the following error: "Error 94, Unit has either been OPENed or preconnected: 00401000 MODIFY [+06d3]". Here is an excerpt of my source code . It seems the problem is with the input/read for the prip.dat file. Please, advise me on fixing this error. Thanks.


write(*,*)'prints 1st line'
OPEN(10,FILE='OUTPUTA.TXT',STATUS='OLD')
c write(*,*)'prints OPEN file'
98 WRITE(*,*) ' Enter magnet and wall data file name >'
READ(*,'(A)')MGNAME
c WRITE(*,*)MGNAME
INQUIRE(FILE=MGNAME,EXIST=FEXST)
IF (.NOT.FEXST) GOTO 98
OPEN(5,STATUS='OLD',FILE=MGNAME)
OPEN(12,FILE='prip.dat',STATUS='UNKNOWN')
c write(*,*)'prints OPEN file'
READ(10,9) Rmin,Zmin,YCLG,XCLG,a,b
write(*,*)'prints Rmin',Rmin,Zmin,YCLG,XCLG,a,b
9 FORMAT(/,18x,F3.1,1x,F3.1,10X,F4.1,1x,F3.1
> ,16X,F4.2,1x,F4.2)
c READ(10,9)KNX,KNY
! c 9 format(///////,20X,I6,I6,///)
KNY= (YCLG-Rmin)/a
KNX= (XCLG-Zmin)/b
write(*,*)'KNX=',KNX,'KNY=',KNY
KN=(KNX+1)*(KNY+1)
KNE =KNX*KNY
* write(*,*)'INPUT THE NO.OF MAGNETS and Walls'
* read(*,*)NCB,NFB
NCB = 2
NFB = 3
write(*,*)NCB,NFB
WRITE(12,64) KN,KNE,KNX,KNY,NCB,NFB

Taiwo

There is a possible conflict between OPEN(5, ... and READ(*,... because 5 may be used as the standard input stream. All unit numbers should start above 6.

Hi, Paul

Can the FTN95 be used for ABAQUS 6.4 (the requirement is Compaq Visual Fortran 6.0 (Update A) on Windwo XP? If FTN 95 is not suitable, could you suggest any suitable products. Thanks.

FTN95 will be OK if ABAQUS 6.4 works with standard Fortran otherwise if you are looking to buy a compiler try contacting Polyhedron at www.polyhedron.com. I assume that www.abaqus.com does not give a list of suitable compilers (or is the information written in Japanese?).

I thought Abaqus only worked with Digital Visual Fortran.

Perhaps, for the next releaes of ftn95, the help file could be amended accordingly, as in the entry for "OPEN" it currently gives the example:
Code:
OPEN(UNIT=5,FILE=’FRED’)

which is unfortunate.
