Script executed by E-Run, a program included with E-Prime experimentation software; saves an executable experiment that was generated from a design (.ES2 file); enables psychology experiments to be run standalone using E-Run. EBS2 files cannot be reverted to the original ES2 experiment design file. This is so the script can be distributed without revealing the intellectual property in the design. NOTE: EBS2 files are the successor to .EBS files used in E-Prime version 1.
