I don't know new versions of PL/I.
For very oldest versions there was depend on variable name used in a program(without DCL).
For first letters I,J,K,L,M,N in a variable name we've got the same results
as by decllare:DCL I BIN(31); - it is default for PL/I.

As Dariusz said...

Variables will be implicitly declared. But this is not advisable in real time. Becoz of implicit declaration you may get run time error.
