Please explain this unexpected syntax

I have encountered some TCL code (well, Jacl code really), that has the statements shown below.

I understand that #1 creates a new java Object, having a value of 1. So far, so good.

What I don't understand is the 2nd statement. I'm used to seeing

set variableName value

So what is this doing?

set 0 value

and why is this after a dereferenced variable?

If you could explain this, and provide equivalent Jython, it would be greatly appreciated.

Thanks

set params [java::new {java.lang.Object[]} {1}]
$params set 0 [java::field com.ibm.websphere.scheduler.BeanTaskInfo class]

Here's the "equivalent" Jython code...

import com.ibm.websphere.scheduler as sch
 
params = [ sch.BeanTaskInfo ];    # class reference
sigs   = [ 'java.lang.Class' ];   # "Signature" identifying "params" type

According to the Tcl documentation, one would use the "array" keyword to define an array.

So, I'm still confused.

array set colorcount {
    red   1
    green 5
    blue  4
    white 9
}

mish33 was completely correct, so gets most of the points.
objects was first, and partially correct, so get some of the points.

Thanks again folks!
