Abstract:

This report gives details of the changes in syntax of PL-516 and the additional constructions added since the publication of Com. Sci. Report No 44 and CCU Report No 9. The principal changes are the use of for becomes an explicit block structure around several declarations case statements and expressions more elaborate for clauses simple conditional labels a range test in conditions the binary operators min and max and a few other minor changes. With the exception of the change, programs which compiled successfully with the older system will still work. Author
