Asking again :-)... I have a program that creates indexes of values stored in raster maps. It needs to tie array to a file on a hard drive and get the file updated when the array is modified during runtime. Also when the the program exits it saves array contents to file so that when it is opened again, it would initiate an array from the file stored. Perl has sdbm and several other modules that can tie hash to dbm files stored externaly. How can this be done in Transcript?
You can use a stack file for storage, saving the array like this: set the customProperties of stack "MyData" to tMyArrayA You can put them back into an array with: put the customProperties of stack "MyData" into tMyArrayA And you can access elements directly in the data stack: get the <elementName> of stack "MyData" You can obtain a list of element keys in the stack properties with: get the customKeys of stack "MyData" For more on using stacks as data files: <http://lists.runrev.com/pipermail/use-revolution/2002-July/006149.html> -- Richard Gaskin Managing Editor, revJournal _______________________________________________________ Rev tips, tutorials and more: http://www.revJournal.com _______________________________________________ use-revolution mailing list [email protected] Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
