Thanks for your reply.
I look at a related forum:, but, it didn't answer my question.
I know I can set string and integer global variables in tSetGlobalVar and access these variables with GlobalMap.get():
(String)globalMap.get("myKey") //the data type of value is String
(Integer)globalMap.get("myKey") //the data type of value is Integer/int
Can I set long, float or double global variable in tSetGlobalVar or not.
Can I do (Long)GlobalMap.get("MyKey") or not.

hi,
globalMap store java Object , so you can store anything as all is object in java.(String, List, Long,etc )
It's also the reason why you have to cast your value from Object to a java type & be able to use methods & functions from that type.

Thanks, Zone.
In tSetGlobalVar, when I add global variable, I cannot specify the variable type.
For example, I add a variable as "myVariable", and set the value as 0.00. I assume it is a Long variable. Than, I use (Long)GlobalMap.get("myVariable") to access this variable. I cannot get the value and the process is canceled.
