Dear Ric did you notice you used that derogatory quite once again "windup merchant". I rest my case
i am happy to repeat for your benefit: that CAS is the present and the future, as 1e-16 is not the same as 1e-309 nor 1e-499, nor 1e-999 etc etc and not the same as zero. For an engineer, sure, yes , they are the same, if it is the final result of a problem. Roger and others have made comments that indeed the trend with J is towards cas. I am also making a contribution for those of 'us' J ers who are not as familiar with pocket pc's and i pod app family and other modern computing devices and services. From many years of personal experience I can say with a great deal of confidence that pocket pc's and such are a GREAT deal of trouble in comparison. Last night's example, I had to dig around to see whether TI N spire cas has updates, it seems they have. Off hand, ie after some time spent, I was unable to access the download, never mind install it. with the i pod app family, this would all be automatic, fully, completely, every bit of it. mys son or one of my exes' put the capitalized letters there, sorry. best wishes. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
