LED (Editor)

LED, the Language sensitive programmers' EDitor, was a powerful screen-based integrated text editor and debugger made by Norsk Data.

It was only available for the ND-500 architecture under SINTRAN III (there was no ND-100 version). LED took advantage of the special ND-NOTIS terminals made by Tandberg Data, but could, like PED, also be used with other terminals supported by VTM, e.g. the VT-100.

The screenshot is of a very early version, A01, which only had language-sensitive support for Fortran and was thus called "LED-FORTRAN-A01". Later versions had language-sensitive support for Pascal and other languages.
