Variables

The standard directive for creating a variable is pc:assign-var. But if you require data type conversion, or if you want to prevent the variable value from being overwritten if it already exists, or both, then use an alternative:

assign:variable	Equivalent to pc:assign-var, but using an XML attribute instead of an XML element.
pc:define-boolean-flags	Adds items to the list of pairs of strings interpreted as boolean true() and boolean false() by "flag-based" string-to-boolean conversion.
pc:GetVariables	Returns the list of Blend variable declarations currently referenced.
pc:LoadVariablesDefault	Retrieves from a file a list of Blend variable declarations, NOT overwriting any existing variables with the same names.
pc:LoadVariablesOverwrite	Retrieves from a file a list of Blend variable declarations, overwriting any existing variables with the same names.
pc:SaveVariables	Save to a file the list of Blend variable declarations currently referenced.
