About the ST eScript Engine

The Siebel ST eScript engine is the default eScript scripting engine in version 8.0. It is compliant with ECMAScript Edition 4. ECMAScript is the standard implementation of JavaScript as defined by the ECMA -262 standard. The ST eScript engine, available in version 7.8 and higher, provides the following:

• Improved Performance. Higher throughput with a lower CPU and memory footprint in cases where you have implemented a significant amount of script. The result is improved performance and lower maintenance on heavily scripted events.
• Scalability. Better performance than the T engine when many users are concurrently executing scripts.
• Enhanced functionality. Support for ECMAScript Edition 4 compliant strong typing. Strongly typed objects allow you more functional scripts and better performance. The T eScript engine, which was available in previous Siebel releases, does not support strong typing.

  Functionality such as Script Assist, script libraries, favorites, and Fix and Go is only available with the ST eScript engine. For more information, see Using Fix and Go and Using Script Assist.

NOTE:  We strongly recommend that customers use the ST eScript engine for the above reasons. In version 8.0 and going forward, Siebel Business Applications are developed using only the ST eScript engine.

For a description of the functional differences in the scripting engines, as well as a description of Strong Typing syntax, see Siebel eScript Language Reference.
