The Question is: My question is around edit. Can you please tell me or point me to where I can find out how to add escape or control sequences to a file using the edit? I used to know what keystrokes to use and how to do it but it has been a long time since I have done it and I can't figure out how to put the esc or ctrl in the strings. I found documentation on how to do it in DCL but not within edit. Thank you, Chris The Answer is : The OpenVMS Wizard cannot and does not recommend direct insertion of the escape character into a file. Techniques such as those described in the OpenVMS FAQ -- loading the value at run-time, either using the technique shown in the FAQ or techniques in programs that use the SMG dictionary of sequences -- are strongly recommended. This because it avoids problems when the file is later editted, and problems that can arise when the sequence differs among various devices. (The SMG dictionary of sequences is especially useful here, and can be used even if SMG itself is not being used for display control. See SMG$GET_TERM_DATA.) For discussions of escape and control sequences, please see the OpenVMS FAQ. If you really want to cause yourself maintenance problenms by embedding the literal escape character or other control character into a file, please see the SPECINS keypad sequence. In EDT, SPECINS is PF1-KP3. For details on EDT and specifically on SPECINS, please read the available EDT documentation. The EDT manual is available among the archived documentation section posted at the OpenVMS documentation website -- please see the OpenVMS FAQ for pointers to the documentation website. Other editors (such as EVE) will use CTRL/V as a quote character for control characters, and you would then immediately follow the CTRL/V with the desired control character using its associated CTRL/key sequence. For details, please see the EVE documentation for QUOTE and CTRL/V.
