[amibroker] Use of regex to extract ticker name from Ami title bar (or anywhere in Ami)

[iceboundbug]

Hello All,

I have an application(MetaMarket) that reads ticker name from MetaStock 
using regex code and that code is 

^((Meta for Windows)|(MetaStock)|(MetaStock Professional)) - ([[]?[^.]
*.mwl - )?([[]?Layout[0-9]+ - )?([[]?Chart[0-9]+ - )?[[]?

I would greatly appreciate if someone can tell me an equivalent code to 
extract ticker name from Ami

Thanks in advance
