Hello there, It does not mean that if the question is not Challenging then let some one else answer it. I am reading about fields in HC Till now I can not find a reason why we need field scripts. I would like some one to give me an example if possible? Another question: when you load from a file into a field how to make HC load the next word into the next line while maintaining the values in the previous lines of the field? Still I have not got an answer to make HC understand that the file to be loaded is not in the HC folder. I mean that the file is on the drive. thanks.

A simple, but very common usage of fld scripts: If a user selects/clicks on a word in the field, the script could do something to give some information to the user about that word. In HC 2.0 this hypertext capability is extended by "Hot Text" and "Group text style". In this way you could put the following script into the fld: on mouseup put the clickedtext into TheString <do whatever you want with the text in TheString> end mouseup In HC 1.* you could define clickedtext by a HT-script but it's a bit slow. You could argue for putting this script into the cd script: OK, but then you will end up with a very, very long and ungraspable cd script. >how to make HC load the next word into the next line >while maintaining the values in the previous lines of the put "MyDisk:OneOfMyFolders:YetAnotherFolder:myfile" into filename open file filename put 1 into i repeat for ever read from file filename until space if it is empty then exit repeat put it into line i of fld myfield put i+1 into i end repeat >file to be loaded is not in the HC folder. >I mean that the file is on the drive. open file "MyDisk:OneOfMyFolders:YetAnotherFolder:myfile" >thanks.

For example if you have a field with money or date information, following little scripts may be useful. on closeField set numberFormat to "0.00" add 0 to me end closeField on closeField convert me to short date end closeField Other useful or necessary message handlers for field scripts are returnInField, enterInField, tabKey.

Yet another use for a field script: To help me in looking for a job, I have a stack with several backgrounds, with several cards per bkgnd. For example, the "company" cards have fields for name, address, contacts, interactions I've had with them, etc. At the front of the stack is an index card with fields for each of the backgrounds. On it is a button that extracts the name field from each of the cards and puts it into the appropriate field, one line per card. Now for the fun part: I want to be able to go to the card for a company by clicking on the company's name in the index field. The following script does this for me: on MouseUp set lockScreen to true put (item 1 of rect of me) & "," & the mouseV into thisLine set lockText of me to false -- the field is normally locked click at thisLine set lockText of me to true put word 2 of the selectedLine into i go to card i of bkgnd "Company Info" set lockScreen to false end mouseUp There may be a better way to do this in 2.0; I haven't seen that version yet. I've used variations of this in a couple of stacks. -- Don Dwiggins "If you think training is expensive, Ashton-Tate, Inc. try ignorance" dwiggins@ashtate.a-t.com -- Derek Bok, Harvard U.
