I think this is the official list: APPEND, ASSIGN, BACKUP , COMP, DOSSHELL, EDLIN, EGA.SYS, FASTHELP, FASTOPEN, GRAFTABL, GRAPHICS, HELP, IN TERLINK, INTERSVR, JOIN, MEMCARD, MEMMAKER, MIRROR, MSAV, MSBACKUP, POWER, PRINT, PRINTER .SYS, QBASIC, RAMDRIVE.SYS, RECOVER, REPLACE, RESTORE, SHARE, SMARTMON, TREE, UNDELETE , UNFORMAT, and VSAFE." I have DOS6.22 and no they didn't, I found most of it was included and that whic h wasn't used anymore was put in a subdirectory of my DOS directory. Some of it no longer ran though, eg EDLIN had a version conflict, but some of it isn't needed. I know at least a few things are definitely wrong as there mentioned in the manu al.

Is it possible to calculate pi to 100 o r more decimal places and print the result on the screen. All I've been able to d o is 15 places and after that it is all zeros so I think it rounds it." The number isn't rounded, that's alll there is. Computer hardware/software is li mited to a set number of digits in a floating point number, that's why you shouldn't r elly on atoms as they can be off somewhere down the line, but as Euphoria uses double s you don't have to worry about it too much. Try printing 2 / 3 to 15+ places, you 'lll find a seven at the end. To go to anything more needs a complex software, which should probablely be written in Machine Code. [Database] I have an idea. Actually it's sort of Netscapes. A Cache. Write the data that ha s been changed to the cache, write it the file later. Only play with that data. Of course it should indicate where the data is supposed to go. Also an offset list of each record might be useful, and only load a record as needed. v Free web-based email, Forever, From anywhere! http://www.mailexcite.com
