Automatic Type Conversion
- When NeXtMidas encounters a parameter in a macro or on the command line, it tries to automatically convert it to the correct type.
  - If it matches the name of a result, that result is used (result substitution).
  - If a caret is used, NeXtMidas will substitute the text value of the named result (result expansion).
  - If the value is inside quotes, it will be a case-sensitive string.
  - If it has curly braces, it becomes a table.
  - If it looks like a number, it becomes a number.
  - If none of the above apply, it becomes an uppercase string.
- When using a caret in conjunction with a string value you will want to quote the results of the expansion.
```
nM> set mystring "Hello World!"
nM> set copystring "^{mystring}"
```
- There is a detailed explanation of Automatic Type Conversion in the NeXtMidas User's Guide under the Result Parameters section.

Java Experts Take Note:
The difference between result substitution and result expansion is that substitution copies a pointer to the existing result while expansion copies the text value of the result.
