50,000 rows does not sound particularly large. Unless you've got many
thousands of columns, it should fit easily into the workspace of any
32-bit (let alone 64-bit) APL, and performance should not be a problem
for column-based operations with this amount of data. You can try
this out using the APLX demo version (free download from
http://www.microapl.com/apl)
- take a look at Quad-IMPORT and Quad-EXPORT for reading and writing
the file.
Although it's not open source, APLX provides free runtimes for
Windows, Mac and Linux.
