The options must be specified in a particular format. The first character in the string is an operator. This determines how the script will apply the argument option to the current value of the quest variable. Immediately following the operator is a numerical argument. The number is negative if the first character is a hyphen ("-"); positive numbers have no special sign. The number ends at the first non-digit character after the optional hyphen. After the argument, there must be a colon (":") followed immediately by the name of the quest variable. The rest of the string is considered to be part of the name.

Example: "=42:meaning_of_life"
