Startup.Int is just a regular program file. Use the <<prxxx>> command where xxx is a prompt for your convenience. The program will pause there and wait for your input. You might find it helpful to use <<Pr$er>> which will display the error message that just occurred.
I'm setting up a standalone (one-directory) XyWrite4-vDosPlus system
that I hope to post when it's working correctly. What's stopping me at
the moment is this:
When I start the program, a few error messages flash by saying things
like "vDosPlus only" (though I am running vDosPlus) and something that
may say "Command not found." How can I pause startup.int so that I can
figure out which command is producing the error message?
Every schoolchild probably knows the answer, but unfortunately I don't.
