- Calling SID
- SID commands
- Some command examples
- SID utility files
- :Calling the program
-
- Syntax:
-
- SID {pgm-filespec} {,sym-filespec}
-
- Explanation:
-
- The SID symbolic debugger allows you to monitor and test
- programs developed for the 8080 microprocessor. SID supports
- real-time breakpoints, fully monitored execution, symbolic
- disassembly, assembly, and memory display and fill functions.
- SID can dynamically load SID utility programs to provide
- traceback and histogram facilities.
-
- : Commands:
-
- Command Meaning
-
- As (Assemble) Enter assembly language
- statements
- s is the start address
-
- Cs{b{,d}} (Call) Call to memory location from SID
- s is the called address
- b is the value of the BC register
- pair d is the value of the DE
- register pair
-
- D{W}{s}{,f} (Display) Display memory in hex and ASCII
- W is a 16-bit word format

-
- S{W}s (Set) Set Memory Values
- s is address where value is sent
- W is 16 bit word
-
- Command Meaning
-
- T{n{,c}} (Trace) Trace Program Execution
- n is the number of program steps
- c is the utility entry address.
-
- T{W}{n{,c}} (Trace) Trace Without Call
- W instructs SID not to trace
- subroutines
- n is the number of program steps
- c is the utility entry address
-
- U{W}{n{,c}} (Untrace) Monitor Execution without Trace
- n is the number of program steps
- c is the utility entry address
- W instructs SID not to trace
- subroutines
-
- Command Meaning
-
- V (Value) Display the value of the next
- available location in memory
- (NEXT), the next location after
- the largest file read in (MSZE),
- the current value of the Program
- counter (PC), and the address of
- the end of available memory (END)
-
- Wfilespec,s,f (Write) Write the contents of a contiguous
- block of memory to filespec.
- f is finish address
-
- X{f}{r} (Examine) Examine/alter CPU state.
- f is flag bit C,Z,M,E or I.
- r is register A,B,D,H,S or P.
-
- : Examples:
-
- A>SID
-
- CP/M loads SID from drive A into memory. SID displays the
- # prompt when it is ready to accept commands.
-
- A>B:SID SAMPLE.HEX
-
- CP/M loads SID and the program file SAMPLE.HEX into memory
- from drive B.
-
- : 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.
