//! # Replace Function
//!
//! Returns a string in which a specified substring has been replaced with another substring a specified number of times.
//!
//! ## Syntax
//!
//! ```vb
//! Replace(expression, find, replace, [start], [count], [compare])
//! ```
//!
//! ## Parameters
//!
//! - `expression` - Required. String expression containing substring to replace.
//! - `find` - Required. Substring being searched for.
//! - `replace` - Required. Replacement substring.
//! - `start` - Optional. Position within expression where substring search is to begin. If omitted, 1 is assumed. Must be used in conjunction with count.
//! - `count` - Optional. Number of substring substitutions to perform. If omitted, default value is -1, which means make all possible substitutions.
//! - `compare` - Optional. Numeric value indicating the kind of comparison to use when evaluating substrings. If omitted, 0 is assumed (vbBinaryCompare).
//!
//! ## Compare Values
//!
//! | Constant | Value | Description |
//! |----------|-------|-------------|
//! | vbBinaryCompare | 0 | Perform a binary comparison (case-sensitive) |
//! | vbTextCompare | 1 | Perform a textual comparison (case-insensitive) |
//! | vbDatabaseCompare | 2 | Perform a comparison based on database settings (Microsoft Access only) |
//!
//! ## Return Value
//!
//! Returns a `String` with the replacements made. The return value depends on the parameters:
//!
//! | If | Replace Returns |
//! |-----|----------------|
//! | expression is zero-length | Zero-length string ("") |
//! | expression is Null | An error |
//! | find is zero-length | Copy of expression |
//! | replace is zero-length | Copy of expression with all find occurrences removed |
//! | start > Len(expression) | Zero-length string ("") |
//! | count is 0 | Copy of expression |
//!
//! ## Remarks
//!
//! The `Replace` function returns a string with substitutions made. Unlike the `Replace` method of regular expressions, this function performs simple string substitution without pattern matching.
//!
//! The return value of the `Replace` function is a string that begins at the position specified by `start`, with substitutions made, and concludes at the end of the `expression` string. It is not a copy of the original string from start to finish.
//!
//! **Important Notes**:
//! - If `start` is specified, the return value starts from that position, not from position 1
//! - The original string before `start` position is not included in the result
//! - Use `count` parameter to limit the number of replacements
//! - Binary comparison (default) is case-sensitive; textual comparison is case-insensitive
//! - Empty `find` string returns the original expression unchanged
//! - Empty `replace` string removes all occurrences of `find`
//!
//! ## Typical Uses
//!
//! 1. **Text Sanitization**: Remove or replace unwanted characters from user input
//! 2. **Data Formatting**: Replace delimiters or format characters in data
//! 3. **Template Processing**: Replace placeholders in template strings
//! 4. **Path Manipulation**: Replace path separators or modify file paths
//! 5. **Case Normalization**: Replace mixed-case text with standardized case
//! 6. **String Cleaning**: Remove multiple spaces, tabs, or other whitespace
//! 7. **Data Import/Export**: Convert between different data formats
//! 8. **SQL String Building**: Escape quotes and special characters
//!
//! ## Basic Examples
//!
//! ### Example 1: Simple Replacement
//! ```vb
//! Dim result As String
//! result = Replace("Hello World", "World", "VB6")
//! ' Returns: "Hello VB6"
//! ```
//!
//! ### Example 2: Case-Insensitive Replacement
//! ```vb
//! Dim result As String
//! result = Replace("Hello WORLD", "world", "VB6", 1, -1, vbTextCompare)
//! ' Returns: "Hello VB6"
//! ```
//!
//! ### Example 3: Remove Substring
//! ```vb
//! Dim cleaned As String
//! cleaned = Replace("Remove   extra   spaces", "   ", " ")
//! ' Returns: "Remove extra spaces"
//! ```
//!
//! ### Example 4: Limited Replacements
//! ```vb
//! Dim result As String
//! result = Replace("one, two, three, four", ", ", " | ", 1, 2)
//! ' Returns: "one | two | three, four" (only first 2 commas replaced)

//!
//! ## Error Handling
//!
//! The `Replace` function can raise errors in the following situations:
//!
//! - **Invalid Procedure Call (Error 5)**: When:
//!   - `start` parameter is less than 1
//!   - `count` parameter is less than -1
//! - **Type Mismatch (Error 13)**: When parameters cannot be converted to appropriate types
//! - **Invalid Use of Null (Error 94)**: When `expression` is Null
//!
//! Always validate inputs when necessary:
//!
//! ```vb
//! Function SafeReplace(text As String, find As String, replaceWith As String) As String
//!     On Error Resume Next
//!     SafeReplace = Replace(text, find, replaceWith)
//!     If Err.Number <> 0 Then
//!         SafeReplace = text  ' Return original on error
//!         Err.Clear
//!     End If
//!     On Error GoTo 0
//! End Function
//! ```
//!
//! ## Performance Considerations
//!
//! - The `Replace` function is optimized and very fast for most use cases
//! - Multiple sequential Replace calls can be slow for large strings
//! - Consider building a new string if making many replacements
//! - Using `count` parameter can improve performance by limiting replacements
//! - Binary comparison is faster than textual comparison
//! - Replacing with empty string is efficient for removing substrings
//!
//! ## Best Practices
//!
//! 1. **Use Meaningful Names**: Name variables clearly (find, replaceWith, not f, r)
//! 2. **Check Empty Strings**: Validate find parameter is not empty when expected
//! 3. **Consider Case Sensitivity**: Choose appropriate compare parameter
//! 4. **Limit Replacements**: Use count parameter when you know the limit
//! 5. **Chain Carefully**: Be aware that multiple Replace calls compound
//! 6. **Escape Special Characters**: Properly escape quotes and special chars
//! 7. **Validate Start Position**: Ensure start is within string bounds
//! 8. **Test Edge Cases**: Test with empty strings, no matches, all matches
//! 9. **Document Assumptions**: Comment why specific replacements are made
//! 10. **Use Constants**: Define commonly replaced strings as constants
//!
//! ## Comparison with Related Functions
//!
//! | Function | Purpose | Returns | Use Case |
//! |----------|---------|---------|----------|
//! | **Replace** | Replace substring | String (modified) | Simple string substitution |
//! | **`InStr`** | Find substring position | Long (position) | Locate substring, check existence |
//! | **Mid** | Extract substring | String (portion) | Get part of string |
//! | **Left/Right** | Extract from ends | String (portion) | Get start/end of string |
//! | **Trim/LTrim/RTrim** | Remove whitespace | String (trimmed) | Clean string edges |
//! | **UCase/LCase** | Change case | String (case changed) | Normalize case |
//!
//! ## Platform and Version Notes
//!
//! - Available in VB6 and VBA (Office 2000 and later)
//! - Not available in earlier VBA versions (use custom function)
//! - Behavior consistent across Windows platforms
//! - Case-insensitive comparison uses system locale settings
//! - vbDatabaseCompare only works in Microsoft Access
//!
//! ## Limitations
//!
//! - Cannot use regular expressions (use VBScript.RegExp for patterns)
//! - Cannot replace with different string based on match context
//! - Case-insensitive comparison depends on system locale
//! - No built-in way to replace with function result
//! - Cannot perform multiple different replacements in one call
//! - When start > 1, characters before start are not in result
//!
//! ## Related Functions
//!
//! - `InStr`: Returns position of substring within string
//! - `InStrRev`: Returns position of substring searching from end
//! - `Mid`: Returns specified portion of string
//! - `Left`: Returns specified number of characters from left
//! - `Right`: Returns specified number of characters from right
//! - `LCase`: Converts string to lowercase
//! - `UCase`: Converts string to uppercase
