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.
