+2. **transpose** - Matrix transpose: `B = A^T`
+   - Tests efficiency of matrix transposition
+   - Usage: `./transpose <matrix_order> <iterations>`
+
+3. **p2p** - Pipeline execution on 2D grid
+   - Tests stencil computation patterns
+   - Usage: `./p2p <iterations> <grid_dim1> <grid_dim2>`

+
+## Implementation Notes
+
+### COBOL Language Features Used
+
+- **Fixed-point arithmetic** with `COMP-3` (packed decimal) for precision
+- **Multi-dimensional arrays** with `OCCURS` clauses
+- **Indexed access** for array operations
+- **Intrinsic functions** for mathematical operations
+- **Command-line argument processing**
+
+### Array Size Limitations
+
+The implementations use statically allocated arrays with these maximum sizes:
+- **nstream**: Up to 1,000,000 elements per vector
+- **transpose**: Up to 1,000×1,000 matrices
+- **p2p**: Up to 500×500 grids
+- **dgemm**: Up to 300×300 matrices
+
+These limits can be increased by modifying the `OCCURS` clauses in the source files, but may require more memory.
+
+### Performance Considerations
+
+1. **Compilation**: Use `-O3` for optimization
+2. **Memory**: COBOL uses significant memory for large arrays
+3. **Precision**: Uses packed decimal for numerical stability
+4. **Timing**: Uses `CURRENT-DATE` function (limited precision)
+
+### COBOL-Specific Adaptations
+
+- **Array indexing**: COBOL uses 1-based indexing (converted from 0-based C)
+- **Variable naming**: Uses COBOL naming conventions with hyphens
+- **Error handling**: Uses COBOL `STOP RUN` for error conditions
+- **I/O**: Uses `DISPLAY` for output formatting
+
+## Troubleshooting
+
+### Common Issues
+
+1. **"cobc: command not found"**
+   - Install GNU COBOL using package manager or from source
+
+2. **Compilation errors about array sizes**
+   - Reduce the problem size or increase array limits in source code
+
+3. **Runtime errors with large arrays**
+   - Check available system memory
+   - Reduce array sizes in the benchmark parameters
+
+4. **Timing precision issues**
+   - COBOL's `CURRENT-DATE` has limited precision for very fast operations
+   - Use larger problem sizes for meaningful timing results
+
+### Platform-Specific Notes
+
+- **macOS**: GNU COBOL works well with Homebrew installation
+- **Linux**: Package manager installations are generally reliable
+- **Windows**: Consider using WSL or Cygwin for GNU COBOL
+
+## Validation
+
+Each benchmark includes validation routines that check:
+- Computational correctness using reference checksums
+- Numerical precision within acceptable tolerances
+- Proper algorithm implementation
+
+Success is indicated by "Solution validates" message.
+
+## Performance Expectations
+
+COBOL performance characteristics:
+- **Strengths**: Excellent decimal arithmetic precision, robust I/O
+- **Limitations**: Generally slower than compiled C/Fortran for numerical computing
+- **Use case**: Demonstrates algorithm implementation in business-oriented language
+
+## Contributing
+
+When modifying the COBOL implementations:
+1. Maintain COBOL coding standards and conventions
+2. Keep array size limits reasonable for typical systems
+3. Preserve numerical accuracy and validation routines
+4. Update documentation for any parameter changes

+      *> NAME:      nstream
+      *> 
+      *> PURPOSE:   To compute memory bandwidth when adding a vector of a given
+      *>            number of double precision values to the scalar multiple of 
+      *>            another vector of the same length, and storing the result in
+      *>            a third vector. 
+      *> 
+      *> USAGE:     The program takes as input the number 
+      *>            of iterations to loop over the triad vectors and the length 
+      *>            of the vectors
+      *> 
+      *>            <progname> <# iterations> <vector length>
+      *> 
+      *>            The output consists of diagnostics to make sure the 
+      *>            algorithm worked, and of timing statistics.
+      *> 
+      *> NOTES:     Bandwidth is determined as the number of words read, plus the 
+      *>            number of words written, times the size of the words, divided 
+      *>            by the execution time. For a vector length of N, the total 
+      *>            number of words read and written is 4*N*sizeof(double).
+      *> 
+      *> HISTORY:   This code is loosely based on the Stream benchmark by John
+      *>            McCalpin, but does not follow all the Stream rules. Hence,
+      *>            reported results should not be associated with Stream in

+      *> PURPOSE:   This program tests the efficiency with which a space-invariant,
+      *>            linear, homogeneous stencil can be applied to a square grid.
+      *>            The stencil uses a 2-point formula in two dimensions.
+      *> 
+      *> USAGE:     The program takes as input the linear
+      *>            dimension of the grid, and the number of iterations on the grid
+      *> 
+      *>                <progname> <iterations> <grid dimension 1> <grid dimension 2>
+      *> 
+      *>            The output consists of diagnostics to make sure the 
+      *>            algorithm worked, and of timing statistics.
+      *> 
+      *> FUNCTIONS: The only "function" used is the "wtime" timer.
