User-defined variables

User defined variables are named and given a value on the command line using one or more “-v” options 

Example

-v:"id=87659876" –v:”UserName=Eric Jones”

Creates the variables

${var.id} evaluates to 87659876  

${var.UserName} evaluates to Eric Jones

If no ambiguity exists, then the suffix can be used without the var. qualifying portion

${id}

${UserName}
