- Subject: g77. Unformatted READ
I am maintaining a suite of Fortran engeneering analysis codes, some of
which date back to about 1970. My problem is with a program that has a
main program and about 12 subroutines. This program compiles and links
and executes ok using g77 under Cygwin, which in turn is under MS Win
XP, but it fails on an unformatted READ when compiled and linked and
executed using g77 under Redhat Linux 7.2. This is all on the same
Polywell PC, which has Win XP and Redhat Linux dual booted. The error
message says unformatted io not allowed. I have tried many
rearrangements of the code, with and without an OPEN statement, but
nothing works under Linux short of reducing the code to just the READ
statement -- then it works.
Note that the error msg does not say something like unexpected end of
file, or file not found, which would lead me to the source of the error.
What conditions can cause the message: "unformatted io not allowed" ?
