calling efs/eSignal global object

[waynecd]

How can global variable names be accessed?
For example in the script below the commented out variables are created via a for loop, but how can they be listed?
What is the reserved word for the eSignal global object so it can be accessed via something like "var variable_Names = Object.keys(object??); " in the bInit block below?

Thanks.

for(var ix=0;ix<4;ix++){
    eval ("do" + ix + "=null");
    for(var iy=0;iy<8;iy++){
        eval("return" + ix + iy + "=null");
    }
