Hi,
Could you please answer my queries:
1. Can we create int variable inside LHS (when)? If yes please give me an
example
You can bind a variable to a field, but I don't think you mean that.
A Number object can result from an "accumulate from" - see the Expert manual.
Otherwise: no.
2. I have a gobal variable which I want to use in timer(int :
<variable> s)
and also in after[0s, <variable> s)
timer is accepting global variable but after is giving error.
[74,200]: [ERR 102] Line 74:200 mismatched input 'after' in rule
"EVENT_SUCCESS"
[0,0]: Parser returned a null Package
Please help out me in this. I would like to use a global variable which can
be changed at runtime.
Changes in global variables are not visible to the Engine; therefore
you cannot do what I think you intend to do.
The parameters for temporal operators must be literals.
