Discussion
RETALL issues RETURNs from nested procedures and functions until the main program level is reached.
When an error occurs in a procedure or function, control is left within that routine unless it contains special error handling instructions. Issuing the RETALL command causes control to return to the main level of PV-WAVE.
note | RETALL stops all currently running PV‑WAVE widget applications. |
