The BY statement variable directives can be used in many places other than TITLE statement where they were first introduced.
I wrote some code (some sort of macro thing) where a variable can contain #byval(variable) and I replace that with the BY value using VVALUEX, and TRANSTRN etc. Of course I could have used another syntax but I don't like to invent my own, where there exists a perfectly good one.
Seems like there should be a way to use what has already been done by SAS to support this kind of replacement, I was thinking a function might exist but did not find one.

ODS DOCUMENT has some automatic variables and I know that TAGSETS.EXCELXP has implemented some BY group support for #BYVAL/#BYVAR/#BYLINE, but as far as I know, it is only documented here in the TITLE statement: SAS(R) 9.4 Statements: Reference, Second Edition -- so your approach of using VVALUEX, etc might be the most flexible.
