One of the biggest differences between OI TCL and AREV TCL is that the latter made use of the VOC file to allow the user to customise commands and even to add their own commands. This does not seem to be the case in OI, rather a cursory examination of the object code for RTI_IDE_TCL suggests that the command list is hard coded.

With this in mind it might be useful to document exactly what commands are supported, and where unclear, what they actually do. For the purposes of this article it will be assumed that the reader is familiar with the syntax of AREV TCL commands. When optional variables are nominated they will normally be in the order TABLE ROW(S) OPTIONS.

So in alphabetical order, the commands are as follows -

Command	Description
.L	Display a popup of previously executed commands.
.n	Copy the nth command to the command line.
ASSISTANT	Launch the Assistant popup.
ATTACH ATTACH_TABLE ATTACHTABLE	Attaches a table.
CLEAR CLEARSELECT CLEAR-LIST	Clears the active select list. Optionally if a name is specified, deletes that list.
CLEARFILE CLEAR_FILE CLEARTABLE CLEAR_TABLE	Clears the nominated table.
COPY COPY_ROW COPYROW	Copies rows from one place to another. Can use an active select list.
COPYTABLE COPY_TABLE	Launch the CopyTable dialog ignoring any command line parameters.
COUNT COUNTROWS	Counts the rows in the nominated table with optional selection criteria
DELETE DELETE_ROW DELETEROW	Deletes the nominated rows from the nominated table, or uses an active select list against the nominated table, or launches a dialog.
DELETELIST DELETE-LIST	Deletes the nominated list.
DICT	Either launches the new table dialog or if a table name is specified, opens the dictionary of that table in the IDE.
EDIT	Launches the appropriate tool to edit programs or record depending on the nominated table. Will accept a list of keys or an active select list. Particularly useful with FIND (q.v.).
EVAL	Compiles and runs the statement
FIND	Find the nominated string in the nominated table. Produces an active select list.Takes Option (G to produce a grid and (X to produce a list. Useful in conjunction with EDIT.
