While we're being nostalgic ... Does anyone remember how they first heard of 4DOS? I first used 4DOS with MSDOS (v5 or v6) but I can't remember how I heard of it.
I was working in a PC and Vax environment, and we were trying to script a number of things. There was DCL on the Vax side, but the basic DOS scripts were too limited, and we were looking to automate our build process.
So, we started looking. Back then, that meant reading Byte, PC Mag, PC Week, PC World, and whatever other computing magazines we could find. It also meant asking on the bulletin board systems (BBSes). 4DOS was one of the ones that showed up in our search.
We looked at things like the MKS Toolkit and a couple of other Unix-based scripting setups, but they were too heavy for the PCs of the day, and/or depended on Unix features that DOS lacked (like background tasks). There was something called VCL, which was a PC DOS version of DCL, but it was too immature. So was GNU.
There were two command.com based/compatible scripting options that we looked at. One was "Command Plus", which appears to be lost in the mists of time. The other was 4DOS.
The Command Plus stuff looked good, and had some features that 4DOS lacked. However, it was buggy as hell, as I recall, and everything was promised to be fixed in the patch release next month, well two months, okay three months, well, six months, because we're going to add XYZ, well, maybe another six weeks, etc.
4DOS wasn't quite as polished in those days, but it was extremely stable. We bought a few copies for the department, but then they migrated everything off the PC to the Vax anyway, making it irrelevant.
I, however, bought a personal copy, and stuck with it. Like Kedit and Windows Commander (now Total Commander), it's one of the tools that I've been using for over 30 years now.
