Hi,

Does anyone know of a way to surpress the error message "Regular expression error nr..." that appears in the BW window when the program tries to do an expr.compile on an invalid expression? We want to use our own error handling for this scenario.

I tried with on.error but nothing.

Thanks,
Bizen

Try with error.bypass = true and afther check the variable e of this way probably you avoid the blank screen

Prueba con error.bypass = true a ver si te deja chequear la variable e posiblemente evites al menos la pantalla blanca

The radio button for bw message window options in option dialog will guide how the bw message are handled. It will also handle error bw message of exp.compile also.

I tried with 'error.bypass = true ' but nothing, any more idea,...

I am not very sure, but I think you can use the compile flags in ttadv2130s000

When there are errors evaluating dynamic expression , pre-defined variable e becomes true . Trap this variable to prevent the bw message window flooded with same message from a running program and to validate a valid expression.
