Why in the following simplest program (three lines) is got "run-time error encountered"?

a= 1.0

print *, a

end

NO ERRORS [<MAIN@>FTN77 Ver 4.03]

1.00000

****** RUN77: run-time error encountered ******

In Main Program at line 3 [file MAIN.FOR]

Maybe the compiler wants a "stop" just above the "end" statement?

With 'stop' message is the same:

1.00000

****** RUN77: run-time error encountered ******

In Main Program at line 3 [file MAIN.FOR]

1: a= 1.0

2: print *, a

3: stop

4: end

Since the program is executing as expected the "error" probably lies with the interaction of the Salford runtime code with the Windows Operating System. This compiler is old and, I presume, you are running with a current version of Windows? Typically commercial programs had to work around bugs in the Windows OS and as the OS improves/changes the workarounds do not always behave as expected.

If my guess is correct then try running on an old version of Windows.

Alternatively try adding a program statement. Although this is not required it may be expected.

I started the program in Win-XP and Win-98. I don't have more old versions. Operator 'program' gives the same. This version of Fortran is not commercial but free for download(http://www.salfordsoftware.co.uk/sof...compilers.html). Really, this message appears only at returning in Windows, and all results are true, but it is not so pleasant to read its each time. Thanks.
