void delete_expression (ESI ptr);

Deletes an expression from the expression stack.

delete_expression deletes an entry on the expression stack pointed to by ptr (it needs to point to the entry tag) from the stack. The entry need not be a simple entity; it may be a complex symbolic expression too. This is achieved by calling next_expression_index and delete_between.

Uses: delete_between, next_expression_index
