Problem with file I/O

Hi, that is what I get when I run my program

PGFIO-F-231/formatted read/internal file/error on data conversion.
In source file r2v435.f, at line number 3980

And here is the code:


.
.
3979 FORMAT(’(I’,I2,’)’)
3980 READ(IBUF,IFOR) INT(I)
3981 ELSE IF(TYPE(1:9).EQ.‘CHARACTER’) THEN
.
.
.

Any suggestions will be more than welcomed.

Cheers, Alberto.
