You can think of TCL as a vastly more powerful version of a batch file, calling other programs from the script with execution guided by the results of previous calls. (In DOS batch you can use things like "if errorlevel" to determine the success or failure of a previous process and do different things depending on whether or not the previous program succeeded. Of course, this requires the programs you run exit with a return code that DOS can store and access. Not all did.) In Don Libes' Expect application written in TCL, I could to things like use TCL to spawn an application to communicate to a remote host that expected interactive execution, and use the TCL "expect" command with a parameter of *what* to expect to grab the prompt from the host and do the next thing needed in response, so I could log on to the remote host and run commands on it and collect results automatically, and not have to be manually controlling the process. (I had one job that ran at midnight, connected to a Unix host, and collected job status reports which it then sent along to an NT server that was accessible from the outside world so the clients could see the status of what we were doing for them. We *weren't* comfortable opening ports on our firewall to let them get directly to the Unix server, and it wasn't necessary. Just put the reports on a server they *could* get to and let them grab them. And this happened automatically while we all slept. > Is it possible to use it to link qpro to quickview. > Could I open quickview while runing qpro. > If anyone would know it would be you. Under a multi-tasking OS like Linux or Windows, likely. Under a single tasking OS like DOS, likely *not*. If it could be done, it would require suspending Qpro and opening Quickview. I recall doing things like that in DOS using TSRs, where the TSR display opened over what the running program had on screen. The currently running program was suspended while the TSR ran, and when you left the TSR, execution resumed on the underlying program. Unless Quickview can be implemented as a TSR to pop up over QPro, I don't see this working. And I assume you would want to do it interactively, and press something like a hotkey combo to pop up Quickview. TCL can't do that for you. It's intended for *unattended* processing. I'm afraid TCL isn't the tool for the job you want to do. > cheers > DS __ Dennis ___ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
Re: [Freedos-user] Tcl for DOS
Dennis I think you were saying that TCL was used to link programs together. Is it possible to use it to link qpro to quickview. Could I open quickview while runing qpro. If anyone would know it would be you. cheers DS ** >From Dale Sterner - MS organic chemistry http://pubs.acs.org/doi/abs/10.1021/jo00975a052 *** $80K In Debt To 2.5 Million Trading Stocks ragingbull.com http://thirdpartyoffers.juno.com/TGL3141/5d93aa4b3f93b2a4b66f9st03duc ___ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user

While I played a bit with dBASE back in the day, I never used FoxPro, and wasn't certain how much of the dBASE programming language it used. The answer seems to be "All of it, with additional newer extensions that make it not backward compatible." That's pretty much what I'd expect, and likely wouldn't need it to be backward compatible. I'd be using FoxPro in the first place because dBASE couldn't *do* what I needed to do. > > (I have Paradox and the manuals, but they are not currently accessible > > and I can't Look Stuff Up.) > see above...

That sounds about right. Requiring a 286 0r 386 wouldn't be a deal breaker for me. I have long since stopped using my original Intel 8088 XT clone, and don't care whether current code might run on it. Someone who wants to be totally retro and still use ancient PC hardware that was real mode only won't be looking at stuff like this. > Ralf __ Dennis ___ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
