## 3.7 `dbx90` limitations

Breakpoints set at the beginning of a routine occur before procedure initialisation; at this point attempting to print or display an assumed-shape dummy argument, a variable with a complicated `EQUIVALENCE` or an automatic variable will produce dbx crashes, dbx90 crashes or nonsensical output. Execution must be stepped to the first executable statement (e.g. using the `next` command or by setting a second breakpoint) before any of these will work satisfactorily.

Strides in array sections must be positive.
