Abstract A sample of 120 production PL/I programs from several commercial computing installations has been studied. Data about the programs in the sample have been extracted by a PL/I scanning program. The statistical results of the study are presented in this document The paper concentrates on statistical data and not on general conclusions. The data are only interpreted to the extent that it is not ill‐defined and misleading. The data profile the use of basic PL/I elements and the structure of programs written in PL/I. The reader of this report will get a better understanding of how PL/I has been used in the commercial environment up to 1974.
