RE: [U2] [UV] reference a variable indirectly?
Yes you can: You get a pr-program to read the file with your actual programs source code open The pre-program inserts the values as values in an array into the source of the actual program i.e. ARRAY1,-1 = PARTNO ARRAY1,-1 = LOTNO ARRAY1,-1 = PARTNAME When all have been inserted it writes the actual program away with a new name Compiles it Executes it The actual program reads the file Does a locate on the ARRAY1 to find the field name and does what it likes to ARRAY2,X (allocates values etc) after that Sounds like fun doesn't it Bob -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Mats Carlid Sent: 13 April 2005 08:36 To: u2-users@listserver.u2ug.org Subject: Re: [U2] [UV] reference a variable indirectly?

[U2] [UV] ACOS problem (floating point numbers)
We have some code that is calculating distances between points, using SIN(), COS() and ACOS(). Occasionally we get the error: Argument domain error in arc-cosine, zero returned This seems to be occurring when two floating point numbers are added together and the result is exactly 1 (or at least seems to be exactly 1), I assume internally the number is slightly over 1. Here's some example code: PRECISION 14 FROM.LAT = -31.29583 FROM.LONG = 119.65194 DEST.LAT = -31.29583 DEST.LONG = 119.65194 VAR1 = SIN(FROM.LAT) * SIN(DEST.LAT) VAR2 = (DEST.LONG - FROM.LONG) VAR3 = COS(FROM.LAT) * COS(DEST.LAT) * COS(VAR2) VAR4 = VAR1 + VAR3 CRT VAR1 = :VAR1 CRT VAR2 = :VAR2 CRT VAR3 = :VAR3 CRT VAR4 = :VAR4 TEMP1 = ACOS(VAR4) TEMP2 = ACOS(VAR4:) VAR4 is displayed as 1, but when TEMP1 is assigned we get the above error message. When TEMP2 is assigned we get no error (i.e. the temporary variable passed to the second ACOS function was a string not a number). Maybe concatenating an empty string during the ACOS() call is the fix for this but it's not really ideal. Anyone have any comments on this? And what happens on your machine?

Re: [U2] [UV] Select returning mv'd list

[U2] [UV] Version Control
Brian, This intrigued. ... version stamp your source code in a way that can be saved into the object code Where do you put it, what do you put there? What platform(s) have you done this on? I know we dig into the unix-level directories for their date ... (PRC checks that the object is newer than the source or it won't deliver (either/both)... and we have script/proc/macros/programs whatever that can search and display those dates from unix) ... but I'm interested in where you went with this. I think it's a good idea. Susan --- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/
Re: [U2] Extending U2 with gci/CALLC -- Factory Floor Automation -Serial
Hi Ed, We use intercall.h mostly for webbased data queries. We have perl CGI pages (Linux/Apache) that first parse and validate user input. If the input is acceptable, an intercall app is executed. The intercall app then opens a connection to a limited copy our production UV server and executes a cataloged subroutine. The data is returned to the intercall program which then returns it to the CGI script which formats it for output as html. Althought this process might sound a little convoluted, it is extremely fast. I've also used this technique to run reports that are printed to a .pdf by the rsync'ed UV back end and then 'pushed out' to the web server for viewing in a webbrowser's Acrobat plug-in. It's pretty neat to be in say, an airport terminal that has wireless access and go to your web site with your PocketPC, run a report and view it as a pdf while waiting to board your plane.
