Identifying procedural structure in Cobol programs
1999
Proceedings of the 1999 ACM SIGPLAN-SIGSOFT workshop on Program analysis for software tools and engineering - PASTE '99
The principal control-flow abstraction mechanism in the Cobol language is the PERFORM statement. Normally, PERFORM statements are used in a straightforward manner to define parameterless procedures (where global variables are used to pass data into and out of procedure bodies). However, unlike most procedural constructs, distinct PERFORMed procedures can share code in arbitrarily complicated ways. In addition, PERFORMs can also be used in such a way as to cause transfers of control that do not
