This is my first attempt with IRC. Is this an appropriate place to ask about making a syntax-parser attempt work?

I won't be asking the syntax-parse questions anytime soon. I'm just wondering if this a decent place to do it. Sometimes I try to generate pict-names from strings so I can use the named picts in slideshow animations. It feels so close after reading aoc-racket's Day 14 (and Day 7) for a few years... But it seems like each time I set out to do it
<bsmal2b>
there are more, better options that I can't quite grasp before needing to move on to something else... So, I'm wondering if this is a place to show a problem or code example and ask for advice..
<bremner>
bsmal2b: sure, as long as you can wait a bit

hiya, new thing i'm sure is pretty simple but i just don't know what to look for i came up with while doing a How To Design Programs exercise
<Chwoka>
one of the exercises is "change every constant number in this sample program to a variable so that it can be quickly redefined later"
<Chwoka>
i defined one of the constants as "baseline-dollar-denominator", then thought, "gosh, that's a handful, i don't want to type out "define baseline-dollar-denominator" every time"
<Chwoka>
had the bright idea of leaving it as-is in the existing program for legibility's sake but having this sort of kludge: "(define (bdd x) (baseline-dollar-denominator x)". but to make that work i had to redefine baseline-dollar-denominator as a function call, meaning that to call it in a program i would have had to write "(baseline-dollar-denominator [the constant value])" anyway
<Chwoka>
surely there's a way to say "make this variable equal to this amount"
<Chwoka>
(BSL)
<Chwoka>
...oh, duh, would it be "(define (bdd x) (define baseline-dollar-denominator x)"?
<Chwoka>
no, that just returns "define: found a definition that is not at the top level in: (define baseline-dollar-denominator x)" as an error...
<Chwoka>
am i just simply not allowed to call "define" inside a "define"?
