C.2. ARRAY()

(beginning Asterisk 1.4)
Sets multiple variables simultaneously (the name is misleading; programmers should note that this does not behave the way an array normally would). ARRAY() can only be used for writing, not reading. Remember to separate values with commas and to escape the commas with a backslash (\), or Asterisk will treat the following characters as an additional parameter for Set()!
; Set var1 to 1 and var2 to 2:
exten => 123,1,Set(ARRAY(var1,var2)=1\,2)


Internal help for this application in Asterisk 1.4:
  -= Info about function 'ARRAY' =- 


Allows setting multiple variables at once

The comma-separated list passed as a value to which the function is set will
be interpreted as a set of values to which the comma-separated list of
variable names in the argument should be set.
Hence, Set(ARRAY(var1|var2)=1\,2) will set var1 to 1 and var2 to 2
Note: remember to either backslash your commas in extensions.conf or quote the
entire argument, since Set can take multiple arguments itself.
