Detailed Description

Compatiblity layer for legacy polynomial operations (over currRing)

Macro defines for legacy polynomial operations used in kernel_page and singular_page. They take no ring argument since they work with currRing by default. Notice that they have different prefix: p instead of p_.

§ currRing

ring currRing

Widely used global variable which specifies the current polynomial ring for Singular interpreter and legacy implementatins. : one should avoid using it in newer designs, for example due to possible problems in parallelization with threads.
