Se hace así:
On abpertura
abrir = baOpenFile( the pathname&"dir/acgi.pdf" , "maximised" )
if abrir>=32 then
nothing
else
alert "hay algún problema con la apertura del fichero"
end if
end
En este ejemplo pongo una ventana de alerta para cualquier tipo de error en la apertura.
Si quieres ser más preciso en los erores te pongo aqui todos los tipos de error que puede hacer.
0 System was out of memory.
2 File was not found.
3 Path was not found.
5 Sharing or network-protection error.
6 Library required separate data segments for each task.
8 There was insufficient memory to start the application.
10 Windows version was incorrect.
11 Executable file was invalid. Either it was not a Windows application or there was an error in the .EXE image.
12 Application was designed for a different operating system.
13 Application was designed for MS-DOS 4.0.

20 Dynamic-link library (DLL) file was invalid. One of the DLLs required to run this application was corrupt.
