MiniRobotLanguage (MRL)
Introduction
The STK. commands provide a powerful and versatile toolkit for managing stacks in MiniRobotLanguage (MRL). Stacks, being Last-In-First-Out (LIFO) structures, are ideal for temporary data storage, recursive operations, and complex workflows. This document outlines the comprehensive stack management capabilities available through STK..
Core Stack Management Commands
- STK.New|$$STK[|s/i/f]: Creates a new stack and returns its handle. Specify the data type (String, Integer, or Floating point) using optional parameters.
- STK.End|$$LST: Releases resources associated with the stack and invalidates its handle.
- STK.Validate|$$LST[|$$RET]: Checks if the stack handle is valid. Returns 1 for valid and 0 for invalid.
- STK.Clear|$$LST: Removes all elements from the stack while retaining its handle for reuse.
- STK.Count|$$LST[|$$CNT]: Retrieves the number of elements in the stack and returns it in a specified variable or places it on the Top of Stack (TOS).
Advanced Management Commands
- STK.Push|$$LST|$$VAL: Adds a value to the top of the stack.
- STK.Peek|$$LST[|$$RET]: Retrieves the top value without removing it.
- STK.Pop|$$LST[|$$RET]: Removes the top value from the stack and returns it.
- STK.Import|$$STK|$$STR[|$$DEL]: Populates the stack using a delimited string. Default delimiters vary by data type.
- STK.Export|$$STK|$$DEL[|$$STR]: Converts stack elements into a delimited string.
- STK.Clone|$$STK[|$$CLN]: Creates a duplicate of the stack, including its type and contents.
Optimizing Stack Usage
1. Leverage STK.Clear to reuse stacks and reduce overhead.
2. Use STK.Validate before operations to ensure handle integrity.
3. Manage large datasets efficiently with STK.Import and STK.Export.
4. Maintain memory stability by invoking STK.End for unused stacks.
Common Scenarios
- Temporary Calculations: Use STK.Push, STK.Pop, and STK.Add for on-the-fly computations.
- Data Rearrangement: STK.Rotate and STK.Reverse help reorganize stack contents.
- Debugging: Print stack content with STK.Show for troubleshooting.
Conclusion
Effective stack management using STK. commands ensures robust, efficient, and reusable workflows. Incorporate best practices and advanced features for optimal script performance.
