Hi Hinko,

The ASCII code for ‘*’ is 42, so you can do

    dbpf <record> ‘*’

I admit this isn’t a particularly general solution, but in an emergency...

Our command-line commands were originally designed for the VxWorks shell which doesn’t allow for large numbers of parameters. Improvements welcomed!
