Revolution for CGI Scripts

How can I foreground an app?
(With my apologies for that case of verbing in the subject :-) I'm writing an alarm clock. When the alarm goes off it would be nice if the app became foremost, so that the user could hit the Any Key to snooze the alarm. So how do I tell an app that's not foremost, or maybe even hidden to become foremost? -- Victor Eijkhout [EMAIL PROTECTED] tel: 865 974 9308 (W), 865 673 6998 (H), 865 974 8296 (F) http://www.cs.utk.edu/~eijkhout/ ___ use-revolution mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/use-revolution

I'm wrong. Well, 99%. You are right, Ian. A very large class of computations will work OK by using signed whole numbers (less than 15 digits). You will want to make sure you don't let the error of a fraction sneak in. Revolution numbers represent integers (in the math sense) up to about 15 digits exactly. I apologize for the confusion. (A simple mental exercise: Imagine some arbitrary non-zero decimal number. Imagine that you convert it to binary. Imagine that you shift the binary point to the left, counting the bits you pass. Shift it to just to the right of the left-most bit that is a 1. Imagine that you cut off the portion to the right of the binary point beyond some number of bits corresponding to mantessa of the floating point number. Note that no ones are dropped off.) Y' know, a number improvement based on Ian's idea would be a lot more feasible than my idea of exact numerals (and applying numberFormat to calculations). Sorry about the error.

Tentative Guidelines for Numbers
To make up for any confusion I helped create and to help contribute to easing the confusion about using Revolution numbers in general, I offer these guidelines on using Revolution numbers. This is based on my experience in computer representations of numbers and only a brief exposure to Revolution. Perhaps this can be a starting point that we can hack at to get something appropriate. 1. Signed whole numbers of up to 15 digits are represented exactly. If results of multiplication, addition and subtraction on numbers in this range are in this range, then the results are exact. Many cases of division and exponentiation are exact. Some other functions might give exact results. (This needs more exploration. Stronger statements about subtraction and exponentiation may be appropriate.) Use numbers in this range if exact results are important. Be careful not to corrupt your calculations with values outside this range. 2. Very large numbers (ignoring sign) or numbers with fractional parts might not be represented exactly. Errors in math functions on such numbers can accumulate. Also, adding a small number to a large number can cause information about the small to be lost and in the extreme case will not cause a change in the number. If you are adding a large number of numbers, consider starting with the smallest first. Avoid using = when you can. Use or for boundary conditions rather than =. In loops use the repeat with form and derive values for each iteration from the loop variable instead of incrementing numbers with fractions. Consider scaling arithmetic into a whole number range. 3. Equality for numbers is tolerant of small differences. Use = for numbers in 2 above only after a couple calculations. Accumulated errors may go outside of what = will consider equal. Use or before = or =. Use any before =. (Actually, I'm guessing about = or =. Some tests need to be run to see if they have the same tolerance as =.) 4. The underlying number representation is carried along in expressions and variables. A value might behave one way when used as a number and other when used as a string (sequence of characters). Not that ( n empty ) will force representation to a string and apply numberFormat. For some values, ( n empty) = n is false. If you can see a number (as a numeral), it has been converted to a string. You can use ( n empty ) to round as defined in numberFormat. Use this, round() and truncate() as need when working with numbers in #2 above. 5. Some fractional numbers are exact, such as 0.5. Take advantage of this. 6. The range for bit functions and base conversion is more restricted than that in #1 above. 7. Very large and very exact numerals can be represented exactly as strings, of course. However, the results of math functions on those will be based on values with the limitations described above. I hope this helps. It needs corrections, additions, clarifications, detailing, wisecracks...

If I'm really confused about Revolution and CGI, I hope these questions give some indication about where I am confused.

Re: How can I foreground an app?
For Macintosh using you store the name of your app in the variable theNameOfMyApp: Do tell application quote theNameOfMyApp quote to activate as applescript I don't think they will be a common solution to all platforms, but I could be wrong.

Re: pasting objects
I think it should be just paste, I wasn't aware of paste having any parameters. It will contain the ID of the newly created object.

Re: File I/O, Arrays, and Databases in Revolution
fields, scientific notation fields, etc. In looking at the Revolution documentation, it appears that I have to somehow read or write each line as a string, then somehow parse each field from this string. So how do you do this efficiently in Revolution? Please note that the files created by the FORTRAN programs are fairly large. open file filename for read read from file until EOF put it into DaFile close file Filename Don't forget the URL command which is MUCH simpler than all this file stuff: put URL (file: theFileName) into DaFile (Note: fileName is a reserved word and shouldn't be used for a variable name - if you colorize your scripts, you'll see and reserved words go red.)

Re: How can I foreground an app?
The problem here is that Applescript's activate command only works on scriptable apps. A Rev standalone doesn't have a scripting dictionary, and isn't directly Applescriptable. However, if you're using a Mac, something like this should work: tell app Finder set the frontmost of application process My Alarm Clock to true end tell ...where My Alarm Clock is the name of your Rev standalone. If you can't use Applescript due to cross-platform consideration, you might try using Rev's Launch command, as in Launch My Alarm Clock I'm not sure whether that would work under Windows, but it's worth a try.

no message to startUp
I made a tiny standalone on Windows 2000, Revolution 1.1.1 B2. It has only one card in the main stack. I don't seem to be getting the startUp message to the card when the application starts.
