You can see these in dialects or domain specific languages (DSL).

For eg. a cron scheduler Rebol dialect:

  at 18:30 do %batch.r
  at 10-Sep-2009/02:00 do %batch.r
  every minute do %job.r
  every month on #15 not [sat sun] do %job.r

And here's an example of an Excel Rebol dialect:

    Excel compose [
        start
        show
        open file (test-file)
        ;alerts on
        alerts off
        ;remove worksheet
        ;close workbook
        ;goto workbook 1
        ;go to worksheet #2
        ;quit
        add a new worksheet
        ;goto cell "B3"
        ;select rows "1:3"
    
        select "B4"
        set value to x
        goto cell "B6"
        change to "Testing"
        select "B7"
        set to "=B4 * B5"
        select "A5:A9"
        change to "=$B$5 * PI()"
    
        set cell 10 2 to 222.22
        set 11 2 to 333.33
        set cells "C2:C6" to 123
        set "D3:E4" "Yeah!"
        change "A1" "=B10"
    
        copy "A1:A9" to "B21"
        cut "B21:B29" to "A18"
    
        select "A5:A9"
        copy
        goto cell "C15"
        paste
        goto cell "D15"
        paste values
        goto cell "E15"
        paste no borders
    
        go to worksheet "Sheet4"
        autofilter "A5" on
    
        open file (test-file-2)
    
        copy workbook "pbtest.xls" "A1:C5"
          to workbook "test-b.xls" "B2"

        goto workbook "test-b.xls"
    
        goto cell "F1"
        cur-cell: current column
        repeat i 3 [
            repeat j 4 [
                goto cell j (cur-cell + i - 1)
                set to (i * j)
            ]
        ]
    ]
