Can I access another application's files or variables?

Hi Cyrille,

You are right, I was using the dot reference incorrectly, as in AFiles("Function.A") rather than Function.AFiles("A"). In hindsight, your form does seem obvious, doesn't it?

The context for file sharing is a program I have for mimicking the R data frame object using the Spreadsheet app of the HP Prime. So far I can load and save CSV files, insert or delete rows or columns, etc. This is why I had asked earlier how to programmatically determine the extent of a spreadsheet, so the user wouldn't need to explicitly define the row and column bounds. For this particular question about file sharing, I can imagine a scenario where a saved instance of Spreadsheet with one data set needs to import from another data set.

I hope to post the program soon, once I finish the documentation, and verify load/save of formulas and cell content other than strings and numbers. I'd like to additionally develop some programs for extracting table subsets based on conditional expressions, support basic R graphic functions like 'plot,' 'boxplot' and 'hist,' and provide command scripting. Eventually, tie all that together into a Prime app with functionality somewhat like RStudio.

I had asked sometime earlier about using the graphic capability of one built-in app within the context of another app instance, and that sounded a bit difficult to do. But we'll see what approach to take (custom code or app context switching) when I get to the graphics part of the project later.

Thanks,
