QBASIC QBLOCKS HOW TO
QBASIC QBLOCKS CODE

To visit a function, type the command func followed by the function name. You can use the func command to visit a function.

Using the file command by itself echoes the file you are currently visiting:ĭbx displays the file from its first line unless you specify a line number: You can visit any file dbx recognizes as part of the program (even if a module or file was not compiled with the -g option.) Visiting a file does not change the current function. You can visit any function or file that is part of the program.

You can visit code elsewhere in the program any time the program is not running. The mapping of / tmp_mnt to / exists by default. Use -c when you try to correct problems due to the automounter because current working directories are inaccurate on automounted file systems. The pathmap command is also useful for dealing with automounted and explicit NFS-mounted file systems with different base paths on differing hosts. If -c is used, the mapping is applied to the current working directory as well. To establish a new mapping from directory from to directory to type: The mapping is applied to source paths and object file paths. The pathmap command creates a mapping from your current view of the file system to the name in the executable image. If you move the source/object files, you can add their new location to the search path. If you move the source or object files, or copy them to a new location, you must either relink the program or change to the new location before debugging. The default directory for the source files is the one they were in when last compiled. The default directory for the object files is the one they were in when the program was last linked.

Before the program starts running and when it is stopped, you can move to, or visit, functions and files elsewhere in the program.ĭbx must know the location of the source and object code files associated with a program. At each program stop, dbx resets the value of the current function to the function in which the program is stopped. Viewing Variables, Members, Types, and ClassesĮach time the program stops, dbx prints the source line associated with the stop location.

It also covers how to use commands to visit code or look up declarations for identifiers, types, and classes. This chapter describes how dbx navigates through code, and locates functions and symbols.
