delete

This function deletes variables from the NCL and frees the symbol name from the symbol table.

Synopsis

	procedure delete(
		data
	)

Arguments

data: Any variable of any type or dimensionality.

Description

This function is used to delete variables from NCL. Although it will accept expression results and literal values, deleting these does nothing to the NCL symbol table. However, when a variable is passed in, all of the memory associated with the variable's value and its reference in the symbol table are removed. Note that if the variable being deleted is an HLU object and the variable contains the only reference to that HLU object, the HLU object will be destroyed. See NhlDestroy for the ability to destroy HLU objects without deleting the variable it points to.
