I have been using an editor in Mainframes (ISPF) which I'm very much comfortable with. Now I'm working on a unix system and I'm forced to use VI. VI is good but since I got used to the editor in Mainframes, I'm having a hard time due to the difference in the command set. Is there an editor in unix which is similar to the editor in mainframes?
It looks like there's at least one free one still maintained: Hybrid Editor XE. There are some dead ones and commercial ones at This page, including a commercial offering called uni-SPF.
You might want to google ISPF Unix or SPF Linux or something similar.
