Alternative to long lines

Context: I have a script in that long lines are being striped.

In bash, I could do this

CURL=/usr/bin/curl

declare -a ARGS=(
  --silent
  --location
  --output /dev/null
  --write-out "%{http_code}"
  --request GET
  --max-time 30
  --retry 3
  "https://httpbin.org/status/200"
)

http_code=$("$CURL" "${ARGS[@]}")

However, ash does not have arrays. Is there another alternative to avoid long lines like I can do on bash in ash or in sh?

Long lines can be split with backslashes:

CURL=/usr/bin/curl

curlWithArgs(){
    "$CURL" \
        --silent \
        --location \
        --output /dev/null \
        --write-out "%{http_code}" \
        --request GET \
        --max-time 30 \
        --retry 3 \
        "https://httpbin.org/status/200" \
        ;
}

http_code=$(curlWithArgs)
