The dot stack displays the entries entered at TCL. Every unique command that is typed at the TCL prompt is saved in a file on the dm account called tcl-stack.

| .? | Displays help. |

| .r | Displays top stack entry and allows modification. |
| .rn | Displays stack entry n and allows modification. |
| .rn/str1/str2 | Replaces string 1 with string 2 in stack entry n. |
| .run/str1/str2 | Replaces all occurrences of string 1 with string 2 in stack entry n. |
