I worked on an early spreadsheet and word-processing system at Lehman Brothers back in about 1984. The system was called Jacquard. The investment bankers built comparative financials in this system and printed them out on 14x11 folded paper. The deal was that you could enter formulas into a bar, with a formula for each column, and drag the bar down to apply the formula to the cells.
Sounds a bit like Lotus Improv or the older Javelin --- any articles on it?
I chatted with Gemini about it seems close: """It sounds like you were using the Jacquard J100 or J500 specifically as a "shared-logic" workstation. ... The Software: AM Jacquard "Data-Rite" While Jacquard was famous for its Type-Rite word processor, the spreadsheet-like functionality for bankers was likely a component of Data-Rite. Here is why your description fits so perfectly: Row-Column Text Format: Unlike modern spreadsheets that are "cell-centric," these early systems were often "record-centric." They functioned more like a flat-file database, with each row a record and each column a field. The "Formula Bar": In Jacquard’s system, you didn't usually put a formula into an individual cell. You entered a "Procedure" or a "Calculation Rule" at the top of a column. "Drawing Down": When you "drew the bar down," you were essentially telling the mini-computer to execute a Batch Process on the text file. It would sweep through the records, applying your math (e.g., Col C = Col A * Col B) to every row in the file.""" It was old when I got there. I never saw any manual; they barely let me touch it.
