This vocabulary provides an easy way to give functions access to local variables within certain limitations.
: foo ( nos tos - result ) locals{ tos nos } @nos @tos + @nos * ;
Note here that locals{ will modify the temporary variable names to match the names you specify.
| Name | Stack (Runtime) | Stack (Compile-Time) | Usage |
|---|---|---|---|
| locals{ | - | -a | Parse for and setup local variables. The parsing ends when } is found. Local variables are created and initialized in reverse order of stack comments. |
| a | -a | a-a | First local variable |
| b | -a | a-a | Second local variable |
| c | -a | a-a | Third local variable |
| d | -a | a-a | Fourth local variable |
| e | -a | a-a | Fifth local variable |
| f | -a | a-a | Sixth local variable |
The initial variable names will be replaced by locals{ each time it is used.
