Variables
${VARNAME} is how variables are used
Variables must be declared before Booleans can be performed (gah - no null value comparitor)
Variables can be nested during setting
- Exten => 123,1,SetVar(BAR=blah)
- Exten => 123,2,SetVar(FOO=3)
- Exten => 123,3,SetVar(NEWVAR.${FOO} = ${BAR})
- This results in ${NEWVAR.3} being set to “blah”
