Name of the calling routine

Is there a function available that will let me test for the name of the Fortran routine that has called my subroutine?

Thanks and God bless!

No, there isn't. About the

No, there isn't. About the best you can do is call TRACEBACKQQ which will generate a traceback - if the program was built with traceback enabled that will contain the names of routines up the call stack. By default this is written to the console (or a popup window), but can be redirected to a file. Probably more complication than you're looking for.

Thanks so much, Steve, for

Thanks so much, Steve, for your as-usual prompt and expert response.

You're very discerning about the complication. On to additional ENTRY points!

Thanks again, and of course ...

God bless!

Please don't use ENTRY! Maybe

Please don't use ENTRY! Maybe pass a code as an additional argument to indicate the caller.

Sorry to challenge your digestion or blood pressure by mentioning ENTRY, Steve! But this is an old dog who knows only old tricks trying to keep an old (45-years-old!) program running that just needs a couple of new options. A lot easier to just point the calling routine into the specific code it needs than to teach the other callers how to identify themselves. ;-)

Thanks again so much for all you do with and for the Forum. You make it so pleasant and understandable for us engineers who have to write code every now and then.

God bless!

40 years ago, there were several incompatible versions of ENTRY (none standard).
