When a Fortran program is built and run with the command (replace '<progname.f>' by the name of the source file, without the '<' and '>')
ftn95 <progname.f> /64 /debug /lgo
these messages are output:
...

Loading s:\lang\ftn95\lgotemp@.obj
Creating executable file s:\lang\ftn95\lgotemp@.exe
Program entered
and an error pop-up appears with the message
**Unexpected switch /SILENT**
and an OK button.
The same program, compiled, linked and run without using /LGO, runs fine.
