Out of curiosity: do you mean you find the job prospects interesting, or the language itself? Because I'd understand if it's a money thing, but... I used to work with COBOL and I wouldn't wish the language on anyone.
There are worse things. I'd rather work on Cobol than in PHP4, or in a project where I have to deal with front-end stuff done using JS and back-end stuff that relies on the NPM package ecosystem.
I'm just saying being forced to use COBOL sucks, because it's uninteresting and outdated technology, and mostly nobody would choose it of their own volition, so most COBOL use falls in the category of "being forced to use it". Interest in retrocomputing aside... and there's better retro stuff to be interested in, anyway!
For me, the best way to review source code is to have it printed, where it is easy to annotate.
In fact i think i will buy me a printer at home for the very same purpose.
Seriously, code printouts are an outdated -- and worse, wasteful -- tool. Maybe they were suitable in COBOL's heyday, but not today.
