At this stage I do not support Index files, reason for not doing so include
1) There are a lot of different implementations of index files on the PC
(Open Cobol has 2 options, Fujitsu has it own, Microfocus has another)
2) A lot of work (coding & testing) and not all versions have the documentation
You could probably edit a 400 MB file if
* You have 2 GB of ram
* You use the RecordEditor - Big File / Edit Big File option
* The Record Length of the file isn't really small (there is an overhead per line so the larger the record-length, the larger the file you can edit).
With 1GB you will be limited to 1/200 MB files and you will need to
change the EditBigFile shell-script / Bat file.
In the RecordEditor/lib directory there is a shell-script/bat file with a name like
EditBigFile.Bat / RecordEditorBigFile.Bat / runEditorBigFile.sh
This script is for editing big files, it is set up assuming at least 2GB of ram. The script will contain a line like
javaw -Xmx1400m -jar "C:\Program Files\RecordEdit\HSQLDB\lib\runFullEditor.jar" "%1"
the -Xmx1400m will give java 1.4GB of ram. The more you give java the bigger the files you can edit (but if you give it to much; the program will not start). Also with 32 bit java you are limited to 1.5 -> 1.7 GB depending on the operating system.
The 1.4GB is for 2GB Widows Vista machine. With Linux / Windows XP you could run with a slightly larger value (assuming nothing else is running).
Even with a optimum setup, 300 -> 500 MB is the limit for 32 bit Java.
You may be able to edit the 400MB file depending largely on haw long
the records are.
Good Luck
