Set Modify controls what style of line modify is used throughout Qedit. The defaults are Qedit-style (^D for delete) in Modify and Before, with MPE-style (D for delete) in Redo only. Set Mod HP forces MPE-style in all places, while Set Mod Robelle selects Qedit-style and Set Mod Qzmod selects Qzmodify (a “what you see is what you get” version of the Qedit-style). If you type Set Modify with no parameters you go back to the defaults.
You also use Set Modify to control placement of the Modify line number and redefine the Qedit-style control codes.
Prompt Option: Where to Print Line Number. Robelle Modify normally prints the line number on the same line as the data. This makes lines look alike in List, Delete, Add, and Modify, and also makes maintaining your tab stops simpler. On the other hand, placing the line number on a separate line makes it easier to press Control-X and re-enter edits. Set Mod Prompt OFF separates line and number (“_” represents the cursor):
/set modify prompt off /modify 10.2 10.2 Now is the time for all good people _ /set modify prompt on /modify 10.2 10.2 Now is the time for all good people _
You can also use the Quiet option not to see line numbers at all.
Replacing Modify with Hpmodify. If you prefer the MPE-style edits provided in the :Redo command, do Set Modify Hpmodify.
Qedit will accept DDD to delete characters, Ixxx to insert xxx, Rxxx to replace with xxx, and U to undo. Other edits include > to append, >D to delete from the end, >Rxxx to replace from the end, and D> to clear the line. HP-style modify does not support tab stops and always prints the line number on a separate line from the data. See :Redo command for a complete list of edits. Hpmodify applies in Modify, Redo, Before and modify in Change and Add.
Forcing Redo to Use Qedit-Style. If you like the Qedit-style modify better than HP style and want to use it even in Redo, do Set Modify Robelle.
Replacing Modify with Qzmodify. To make Qzmodify the style throughout Qedit, use this command:
SET MODIFY QZMODIFY [TAE|TAEOFF]
(Default: disable Qzmodify)
The TAE options apply only if you have a Telamon Type Ahead Engine:
- TAEOFF means to disable your Type Ahead Engine.
- TAE means to enable your Type Ahead Engine.
- The default is to ignore the Type Ahead Engine.
Qzmodify replaces the regular Qedit modify with a routine that allows “visual” editing on HP terminals. Once you do Set Mod Qzmod, all modify operations within Qedit will use Qzmodify, including Before, Redo, modify from within Change, and the Modify command. To disable use of Qzmodify, enter Set Modify with no parameters.
Qzmodify uses single-character reads, which you may find are a significant drain on the resources of your HP e3000. Qzmodify will work over DS lines, but will be very slow. However, avoid Control-Y and Break, because there are bugs in DS that confuse the state of the terminal. Qzmodify does Setmsg OFF on your session and Setmsg ON when it is exits; use Set Vis Msg OFF to leave Setmsg OFF all the time.
For details on the Qzmodify edit codes, either enter Qzmodify and type Control-Q or see the Modify command.
Changing the Control Characters. You can change the default code assigned to any function in the Qedit Modify command by using Set Modify:
^Set Modify (B ^x D ^x T ^x G ^x L ^x O ^x V ^x A ^x)
The Modify command uses nonprinting control characters for function codes. These characters have ASCII values between 1 and 31 which are generated by holding down the CONTROL shift key while striking another key. For example, the code for Before is Control-B (^B, decimal 2). Because many terminals use specific control codes for local functions (i.e., Control-B may clear the screen), Qedit allows you to change the control codes assigned to Modify functions. However, the control codes for Qzmodify cannot be redefined.
Using Set Modify, any or all of the control function codes can be changed. The current codes are displayed in the Verify command. Each control-function change consists of the first letter of the function name, followed by a space, then the circumflex character and the desired control letter. For example:
/set modify (t ^Z)
This specifies that Control-Z (equal to decimal 26) is the control key for the TERMINATE function. Certain control codes are not allowed and will be rejected. Each function must be assigned a unique control character from among these:
A B C D G K L N O P R T U V W Z \ ] ^ _
