# Table of Contents



When exporting the following code block using indentation, it is not
possible to know where the source code ends and the results of
evaluation starts.

    echo "echo ab"
    echo "seq 1 2"

    echo ab
    seq 1 2

The language of the following code block will be `sh` because `dash`
doesn't belong to `org-md-lang-export`

    result=0
    
    for i in $(seq 1 5)
    do
      for j in $(seq 1 5)
      do
        result=$((result + i + j))
      done
    done
    
    echo "$result"

    150

The language of the following code block will be the same as the one
used in Org Mode because `R` doesn't belong to `org-md-lang-export`

    data(Loblolly)
    
    max(Loblolly $ height)
