When the debugger session begins, the debugger may issue several different kinds of warnings.
A warning may be issued if the source file is newer than the program and/or STB file. Out-of-date files may be present for any of the following reasons:
The following is an example of this type of warning message.
**Warning** Source file newer than program and .stb files for main.
A warning may be issued if an STB file for a module compiled in debug mode is not found. This would be an error if the debugger could not find any STB files; however, the debugger will issue a warning only if one or more (but less than all) STB files are missing.
The following is an example of this type of warning message.
**Warning** No debug data for environment ** Source file "y.pl1" ** Symbol table file "y.stb"
