For maximum flexibility, the DEBUG.xxx and TRACE.xxx statements are actually compiled as:
xcall EVTWIN, opcode, string {,optional args}
where opcode is made up of the following parts:
Value |
Meaning |
|---|---|
&h0001 |
Open |
&h0002 |
Print (or pause) |
&h0003 |
Close |
&h0100 |
Debug (versus trace) |
&h0200 |
Pause (wait for double-click) |
EVTWIN.SBR is included in A-Shell, but if you don't like the way it works, you could theoretically replace it by using an alias and supplying your own SBX. Also, under AMOS, or versions of A-Shell prior to 4.9.963, if you want to be able to run programs containing such statements and compiled with /RC, you would need to supply a dummy EVTWIN.SBR, so that the statements had no effect, or if you are really ambitious, create one that does something useful. The simplest null SBX would be a program containing just an END statement, with the RUN renamed to SBX.
