in reply to no visibility to global hashref ?!?

Hello kerchunk, and welcome to the Monastery!

I’m sorry, I don’t understand what you are asking:

But I don't seem to have any visibility of the target hashref outside of measureHashrefLength...

I assume the “target hashref” is $allActivity_hashref, but I don’t find any reference to measureHashrefLength in the code shown?

In any case, note that although you’ve commented the declaration of $allActivity_hashref, etc., under “globals”, variables declared with my are lexicals, not (package) globals (which are declared with our). A lexical variable declared at file scope, as here, is visible throughout the rest of the file, but not within code in other files using the same package.

Please clarify where you want to access the “target hashref”, and how it fails to be visible.

    Ooof. replace "measureHashrefLength" with "measureFieldLength" in my explanation. And the source for measureFieldLength is $allActivity_hashref and the target is $allActivity_fieldLength_hashref. If one were to look in the sub measureFieldLength one could see it's reading rows from $allActivity_hashref and populating $allActivity_fieldLength_hashref. HTH, kerchunk

      So... How does it fail to be visible?

      Update: If 'it' is meant to be  $allActivity_fieldLength_hashref I think Laurent_R has put his finger on the problem below.

      How 'bout you replace it yourself? Because you posted as a registered user (most desirable, IMHO), you can go back and edit your post. However, please be sure the edits are readily apparent via  <strike> ... </strike> or  <del> ... </del><ins> ... </ins> tags, or an "Update: ..." paragraph or paragraphs added at the end of the post — or both! Uncited changes to a post just make the replies of other monks seem incoherent. Please see Markup in the Monastery, Writeup Formatting Tips, etc.
