	3	+ Variable is a container that holds a value and can be called in the iXPath Scenario. The importance of variables is to make flexibility in using some values without referring to their origins.
3	3
	5	+There are 2 types of  variables:
4	4
	7	+* System variables
	8	+* Local variables
5	5
	10	+To call a variable, we should put it inside ${}. Eg: for a variable named ‘iXVar’, it can be called as ${iXVar}.
6	6
	12	+== System variables ==
7	7
	14	+System variables define some default values in the system, and they can be called by users several times.
8	8
	16	+Here is the list of system variables :
	17	+
	18	+1. At the declaration of the scenario:
	19	+1*. iXSession: it returns the ID of the current session.
	20	+1*. iXSessionPath: gets the Path of the session folder.
	21	+1*. env: name of the environment.
	22	+1*. inputFile: this variable collect all input files in one list.
	23	+1. For a **mail listener : **
	24	+1*. iXFrom: refers to the sender of the mail.
	25	+1*. iXSubject: refers to the mail subject.
	26	+1. For an **AS2 listener **:
	27	+1*. iXFrom: return the value of the AS2 sender.
	28	+1. All connectors declare a system variable of type BpmnFile, the connector variable uses a bunch of functions to handle the list of BpmnFiles that will be detailed in the table below :
	29	+1*. (((
	30	+(% style="width:884px" %)
	31	+|(% style="width:150px" %)**Function**|(% style="width:365px" %)**Description**|(% style="width:367px" %)**Use**
	32	+|(% style="width:150px" %)Get(i) |(% style="width:365px" %)Get a file with index number "i" from the BpmnFile list, the indexes begin from 0 as the first element, and so on.|(% style="width:367px" %)(((
	33	+if we have an XmlToXml connector named "XmlToXml1" we can get __the second__ BpmnFile as :
	34	+
	35	+${XmlToXml1.get(1)}
	36	+
	37	+NB: we will make examples on the same connector "XmlToXml1".
	38	+)))
	39	+|(% style="width:150px" %)getTrkValues()|(% style="width:365px" %)Return the Tracking values from a BpmnFile.|(% style="width:367px" %)Eg : ${XmlToXml1.get(0).getTrkValues()} returns the tracking values of the first BpmnFile.
	40	+|(% style="width:150px" %)path()|(% style="width:365px" %)Return the absolute path of the BpmnFile.|(% style="width:367px" %)Eg : ${XmlToXml.get(3).path()} returns the path of the __fourth__ BpmnFile
	41	+|(% style="width:150px" %)fileName()|(% style="width:365px" %)Return the name of the BpmnFile. |(% style="width:367px" %)Eg : ${XmlToXml1.get(2).fileName()} retrieves the name of the third BpmnFile.
	42	+|(% style="width:150px" %)extension()|(% style="width:365px" %)Returns the extension of the BpmnFile.|(% style="width:367px" %)(((
	43	+Eg : if we want to get the extension of the first BpmnFile, we will proceed as below :
	44	+
	45	+ ${XmlToXml1.get(0).extension()}
	46	+)))
	47	+|(% style="width:150px" %)fullName()|(% style="width:365px" %)Returns the file name + its extension  |(% style="width:367px" %)Eg : ${XmlToXml1.get(0).fullName()} returns the full name of the BpmnFile.
	48	+|(% style="width:150px" %)size()|(% style="width:365px" %)Returns the size of the BpmnFile in megabit.|(% style="width:367px" %)(((
	49	+Eg : ${XmlToXml1.get(0).size()} returns the size of the first BpmnFile.
	50	+)))
	51	+|(% style="width:150px" %)type()|(% style="width:365px" %)Returns the type of the BpmnFile|(% style="width:367px" %)(((
	52	+Eg : To get the type of the second BpmnFile ,
	53	+
	54	+${XmlToXml1.get(1).type()}
	55	+)))
	56	+)))
