I have just come face-to-face with the 32K (or there about) limit on the amount of material that can be stored in a field. The application is that I am reading raw data from a text file into a field and then doing various data analysis procedures on this. Does anyone know of any utilities to get around this limitation eg reading text into a number of fields and then have that appear as a one big field? Does HC 2.0 have a similar limit on field length. Thanks for any assistance, Peter Evans

There is no limit on how much you can put in a variable, so you can read the data into a variable. |Does anyone know of any utilities to get around this limitation eg |reading text into a number of fields and then have that appear as a |one big field?

Its actually a limit in the Macintosh TextEdit, which we chose to use so we could be compatible with the Script Manager. The SM allows us to work with non-Roman languages (Kanji, Hebrew, Arabic, etc...). Steve Maller HyperCard Engineering Team Apple Computer ------------- I speak solely for myself in these matters

Fields have two big advantages over variables: they can be seen (and edited) by the user, and they are non-volatile (the data is still there if you quit HyperCard and resume later). Variables have two big advantages over fields: there's no size limit, and they are *much* faster to manipulate in HyperTalk. You could keep your data in a variable while you're processing it, and in a file when you're not. That gives you speed, size, and permanence with relatively little pain.
