Question:

Can I use the same line numbers or line labels in different
subprograms that are compiled in the same source file?

Response:

No, but you can use the same line numbers or line labels if the
subprograms are separately compiled.

Line numbers and labels are local to the compiled module in which they
occur. Line numbers and labels must be unique within a given compiled
module. You do not need to worry about duplicate labels in separately
compiled modules.

Note that using the REM $INCLUDE metacommand to include source code
from a separate file is similar to putting the two sources into one
file. Any files included at compile time with the REM $INCLUDE
metacommand are considered as part of that module, and are included in
the .OBJ file.

This information needs to be added to Section 9.2.1, "Using Line
Labels", on Page 160 of the "Microsoft QuickBASIC Compiler" manual for
Versions 2.00, 2.01, and 3.00.
