String Expressions

In Bright Pattern Contact Center, you may work with data as variables stored as values, which may be specified as strings or expressions. A string is a sequence of characters that is generally understood as a data type; often a string is implemented as an array of bytes (i.e., words) that store a sequence of elements. An expression will produce a data type such as string.

What follows is a list of tips regarding string expression structure.

  • An expression starts with = sign, e.g. in "a=b" assignment block, ="string1"+"string2" in the value field would result in "string1string2". If you omit the equal sign, the result would be "string1"+"string2"
  • Strings are enclosed in double quotes (e.g. "sample string").
  • Backslash can be used to embed a double quote phrase within a string (e.g., "sample string \"embedded quote\" sample string").
  • Backslash can also be used to insert literal new-line and carriage-return symbols using the \n and \r notation (e.g., "sample string\n with new line in it").
  • Strings can be concatenated; that is, strings can be linked together as in a chain (e.g., = "string 1" + "string2" produces "string1string2", or if $(var1) = "help" and $(var2) = "me" then $(var1)$(var2) returns helpme).
  • Strings themselves or string expressions cannot span multiple lines (i.e., while embedded, \n is OK, but the actual new line is not).
