I am struggling with getting “computed” (environment) variables to work.

I have tried and looked at :

https://docs.github.com/en/actions/using-workflows/workflow-commands-for-github-actions#multiline-strings

Github Actions, how to share a calculated value between job steps?

https://github.com/GuillaumeFalourd/poc-github-actions/blob/main/.github/workflows/53-concatenation.yml

Most of the examples I have seen are setting a SINGLE computed-variable, not multiples.

At the end of this, I would like to see

FullSentence=The green dog jumped in the air 555 times.

where 555 is the GIT_HUB_RUN_NUMBER from https://docs.github.com/en/actions/learn-github-actions/variables#default-environment-variables

Below is my latest attempt, trying to mimic what is coming from docs.github link above about multi-lines. SELECTED_COLOR is straight from the docs.github example. (I’d added more items to get a full sentence).

Here is my yml contents

name: Deploy

on:
  push:
    branches: [ "main" ]
    paths-ignore:
      - 'README.md'
      - '.github/**'

  pull_request:
    branches: [ "main" ]

  # Allows you to run this workflow manually from the Actions tab
  workflow_dispatch:

env:
  THE_ANIMAL: dog

jobs:
  jobOne:

    runs-on: [ your_runner_here ]

          {
          run: echo "SELECTED_COLOR=green" >> "$GITHUB_OUTPUT"
          run: echo "SELECTED_ANIMAL=dog" >> "$GITHUB_OUTPUT"
          run: echo "SELECTED_COUNT=${GITHUB_RUN_NUMBER}" >> "$GITHUB_OUTPUT"
          }

          theSelectedAnimal: ${{ steps.idabcxyz.outputs.SELECTED_ANIMAL }}
          theCount: ${{ steps.idabcxyz.outputs.SELECTED_COUNT }}
        run: |
          echo "THE_ANIMAL=${{ env.THE_ANIMAL }}"
          echo "theSelectedColor=$theSelectedColor"
          echo "theSelectedAnimal=$theSelectedAnimal"
          echo "theCount=$theCount"
          echo "FullSentence=The $theSelectedColor ${{ env.THE_ANIMAL }} jumped in the air $theCount times."
