To avoid the 2048 string length constraint in reading and writing files, can I use seq.getc$ (testing chr$(10) and chr$(13) for the end of line) and seq.putc$ ? I didn't find any example in Baan IV.

Can someone send me some example and advice ?

Thank you.

You can use seq.puts$ to write data to file, but you can only write one character at a time.
Syntax is puts$(char, file pointer)

yes, I know.
My doubts were how to know the end-of-line. I compare the return string with chr$(10) (\n LINE FEED) or the previuos and the actual char with chr$(10) & chr$(13) (\r\n CRLF) in order to find out if the line is at end. Then I process the line and write char by char another record file.

Up to now it seems to work.

Thank you.

The return value is The character written to the file. Or an empty string if the end-of-file was reached or an error occurred.
The last system error is available in the e variable, for values of e u can refer errors code from Baan Help
