There is an alternative though. As you found out, the pasting process in big pastes is slow because of the large amount of overhead involved repainting the screen. I have the disadvantage of not being able to tell the difference between typed characters and pasted characters. I wrote some code to be able to download pasted text directly into a window. The command is ASCII.RECV. There are two versions of it. One version uses an INPUT statement to enter the pasted text. After I wrote it, I became aware that some flavors filter out special characters, like the esc character, from the line that is input. Ergo a second version which uses byte-by-byte input. The version you have is the first version I wrote. I am not sure if the flavor you are using filters the input line, so, in case it does, I have attached the second version in a zip file. This is important because the sequence "esc esc " ends the input. If the first version does not work, use the second.

There is a specialized interface for all VGERBP modules. It is EV. Every dynamic command has VGER$ as a prefix. This was done to ensure I did not overwrite anyone else's programs. The part to the right of the $ is call its command name. With EV you only have to enter the command name, i.e., EV LX would open VGER$LX, or EV ASCII.RECV for VGER$ASCII.RECV.

There is a command to set all the triggered code properly. The command is PREP. When editing an mvToolbox module, type PREP UNIDATA (or D3 or UNIVERSE, depending on your flavor) and it will set the triggered lines properly. In LIST.EDIT, put your cursor on the module and type PREP D3 (UNIDATA / UNIVERSE), or if you are doing all, type PREP ALL D3 (UNIDATA / UNIVERSE).

What I would suggest, would be to paste the code into a ascii text file on the server, and create a VOC entry pointing to its folder. Then you would have a staging file for future enhancements/fixes. All you would have to do is save it there, and edit it directly, or just copy it over to VGERBP. There are a NUMBER of ways to get it into VGERBP. Look at these commands: OVL, COPY.TO, SAVE, and LOAD.
