Optimizing cobol object code instruction path length with respect to perform statements

摘要

A method for optimizing instruction path lengths in a compilation of COBOL source code with reference to PERFORM statements requires a two-step procedure in which the control transfer relationship among the PERFORM statements and associated procedures is characterized as a vector of attributes, and a second step in which the vectors are interpreted for any given PERFORM statement such that, where indicated, the code of the procedure or simplified linkage code will be substituted for the PERFORM statement.
