SID UTILITIES SID utilities, HIST.UTL and TRACE.UTL are special programs that operate with SID to provide additional debugging facilities. The mechanisms for system initialization, data collection, and data display are described in the CP/M SID User's Guide. The HIST utility creates a histogram (bar graph) showing the relative frequency of execution of code within selected program segments of the test program. The HIST utility allows you to monitor those sections of code that execute most frequently. The TRACE utility obtains a backtrace of the instructions that led to a particular breakpoint address in a program under test. You can collect the addresses of up to 256 instructions between pass points in U or T modes. HELP>
