Abstract
The aain a.1.m of the project is to design and impleaent a systea facility to enhance the debugging capability of the exiting FORTRAN debugging features. This facility is known as FORTBAN .PBOFILEB. Such a protile.r will provide Fortran p.rograa user with various run-tiae statistics on the e~ecution of his (or her) p.rogra.a. These run-time statistics includes the frequency counts of statement execution, variabl.e (and array) referencing and procedu.re calls. Such inforaation will te extreaely useful fo.r debugging and OJ:timising of n difficult n prograas. A trace facility is also included to enhance the bug dectection capability of the profiler. The designing and implementing part of the profiler"based mainly on the concepts ot !odular Prog.ramming , Classical Debugging and Basic block. !he insufficient debugging features available in current computer installation , especially in Scientific applicat.1.on a .tea , forms the basic idea of iaplementing this Rrofiler. Otbe.rs like the techniques of Coapaction of program statement, Decoding of prograa key words, and Classification of statement bloc~ are used in implementing the features of the Profiler. Lastly programming language , PL/I is cbos~ as the implementing language for its general and multi purpose application language.
