– PL/I included the best of ALGOL 60 (recursion and block structure), FORTRAN IV (separate compilation with communication through global data), and COBOL (data structures, input/output, and report generating facilities), along with a few new constructs
– PL/I was the first language to have programs allowed to create concurrently executing tasks, the possibility to detect and handle 23 different types of exceptions, procedures allowed to be use recursively, pointers included as a data type, and reference to the cross sections of arrays
