I, too, am inclined to agree with Mr. Sample, but the issues may be more complex.
Unfortunately, the TS (Topic Starter) chose to cut off the terminal emulator he is using in the PNG files he chose to share with us so we have no idea what emulator he is using.
The more advanced terminal emulators support two modes to paste data. One mode roughly corresponds to the usual Windoze convention and will result in what the TS appeared to show us. A second mode - my emulator calls it "block" mode - operates more like we would expect, where the text is inserted into the ISPF edit screen only in the ISPF input area and does not overlay the sequence number area. As I recall the IBM 3270 emulator offers this option, but I cannot speak about other emulators. I no longer endorse the emulator I use as its vendor has chosen to drastically increase its price and their support policy is not acceptable so I will not mention it. It has been more than 20 years since I used any version of the IBM emulator, and my knowledge of other emulators is limited.
One emulator I do use, though no longer in a production use, is the Vista 3270 emulator. Its price is reasonable and, as of a few years ago, anyway, its product support was excellent. I just started it (for the first time in several years) to test its paste capabilities. It appeared to use block mode paste, but I could no longer find where it was set.
I do endorse Mr. Sample's idea: check the documentation and the configuration options.
One other option is to upload text data (e.g., a Windoze ASCII file) as a text upload and edit the data set created by the upload, and forget pasting data from, say, a Windoze notepad display.
