Hi, I have a question regarding sorting in HyperCard. If I have a whole bunch of cards with a bkgd field that contains a date in short format (6/9/89, for example), what is the best way to sort this in chronological order? Is there a way in HyperCard or has anyone written an XCMD to do this? Also, some of the dates are in the format (6-9-89) and some are (6/9/89), what is the best way to convert the dashes to slashes? Am I going to have to write a script that does this? (ugh!) Thanks for the help! /lih ___________________________________________________________ """""""""" / \ | @ @ | | Andrew "Fuz" Lih Columbia University Center | < > > ___/ Academic Computing for Computing Activities | \ \__/ / <___ / \____/ \ lih@cunixc.cc.columbia.edu AJLUS@CUVMB.BITNET / \ lih@cs.columbia.edu ...rutgers!columbia!cunixc!lih | \__________________________________________________________/ =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= """"""" Andrew "Fuz" Lih Columbia University Center | @ @ | Instructional Computing for Computing Activities < ^ > \ - / lih@cunixc.cc.columbia.edu AJLUS@CUVMB.BITNET --- lih@heathcliff.cs.columbia.edu ...rutgers!columbia!cunixc!lih =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

A sample script would be; --In a sort button perhaps on mouseup repeat with x = 1 to the number of cds go cd x convert fld "dateField" to secs end repeat sort numeric by fld "dateField" repeat with x = 1 to the number of cds go cd x convert fld "dateField" to short date end repeat end mouseup I'm sure there's a more elegant way to do this, but this gets it done.
