Get memory allocated by table

Dear community,

I read the solution somewhere, but couldn't find any more.

Is there a command in JSL to get the information, how much memory is allocated by a certain table, and how to use it?

I'm struggling with large data tables (~1 million rows each, 200 cols, ~100 MByte on disk).

Opening two tables and concatenating manually makes an error due to tight memory (8GB, JMP64bit, Win7, pagefile increases to 20GB, exceeding disk space).

What options do I have to improve memory efficiency?

 

Compressing all columns only gives slightly smaller disk space.

Opening "private" and Concatening via JSL will help?

 

Thanks and best regards,

  Georg
