with calling recursive/iterative function that findsminValue of type Int - gamg7 - May 7, 2016

Hello,

I've currently got an assignment utilizing the m68000 processor. To objective of the assignment is to call a recursive function that finds the minimum value and sort it using one of two methods.

The basic idea is that the minimum value is either the first element of the list, or it is the minimum value from the rest of list. You should correctly implement the above psuedocode in your findmin.s file.
Here is the high level abstraction I am using for pseudocode:

Code 
int findmin(int* vals, int count)

 {

    if(count == 1)

    {

        return vals[0];

    }

    else

    {

        int minrest = findmin(vals+1,count-1);

        if (minrest < vals[0])

        {

            return minrest

        }

        else

        {

            return vals[0]

        }

    }

}

Here is my current code, as you can see I've just started and I've currently got an error:

Code 
start:      initIO                  * Initialize (required for I/O)

            setEVT            * Error handling routines

*        initF            * For floating point macros only    

    *move hardcoded values into d0 and d1

    move.l #0,D0

    move.l #1,D1

    cmp.l D0,D1

    bgt less

    lineout greater

less:    

    lineout less

            break                   * Terminate execution

greater: dc.b 'greater'

less: dc.b 'less'

Please help when possible, thank you.

the error is because you are using the symbol "less" in 2 x places

less:
lineout less

and a second time

less: dc.b 'less'

call the second one "lessmsg" or something
