Lucid 3-D

Lucid 3-D^[1] was a spreadsheet package that began in the MS-DOS era;^[2] Windows support came later. ^[3][4]

History

Sam Redman^[5] and Michael Stanford^[6] incorporated as PCSG corporation (Portable Computer Support Group).^[7]

Their Lucid 3-D spreadsheet was marketed by Dac Software of Dallas, Texas.^[8]

Features

Lucid 3-D was considered noteworthy at the time for being "the only major memory-resident spreadsheet available for the PC".^[9]

The selling point of the product was being "three dimensional. Any cell of the spreadsheet can contain a complete other spreadsheet that you can access with a single keystroke."^[10]

Another technical feature was what their ads called "not only minimal recalc, but background recalc".^[11]

The Windows versions could display "up to nine overlapping spreadsheet windows".^[1]

File extension

Data files were stored using the extension ".lcw" (Dot LCW).^[12]
