print a tag value

[acer]

What is the correct way to print the value of a tag in a report? For data:

2021/02/09  payname

  ; num: 1

  Asset:Account  $5.00

  Expense:Account

2021/02/08 otherpay

  ; num: 2

  Liability:Account  $150.00

  Income:Account  

How do I print the value of num in the report?  When trying 

reg --format " %(num) \\n"

I get this error message:

While calculating format expression:

  num

While evaluating value expression:

  num

Error: Unknown identifier 'num'

With the command:

reg --format " %num \\n"

I get:

Error: Unrecognized formatting character: n

Of course...

I guess I could have also escaped the quotes:

reg --format "%(tag(\"num\")) \\n"

Thanks!
