1 | message module not initialized |
2 | message output disabled |
The message must be contained in the system entity T_MESSAGE.
If you pass a zero pointer as message name, DataView will directly output the text passed in the parameter st1.
Each message occupies one row in the message window. You can output several messages in the message window below each other if you defined a multi-line message window via the dal_mes_set function.
Messages that get longer than one row because of additional entries are correctly broken into lines by DataView. However, the message window is not automatically scrolled upward, so that the user may only see the first line. For this reason you should prefer short messages.
