The Debugger executes the .4go module, but it displays lines from the .4gl source file. Because the source file has been changed since the module was compiled, the lines that the Source window displays might not correspond to the statements in the compiled program.
If you change the source code in a .4gl file, you must recompile it. If your program includes several modules, you must also concatenate the compiled modules before you start debugging. Also check if files exist with both the .4go and .4gi suffixes for this program. Even if your .4go file is the appropriate recompiled version, the Debugger first attempts to interpret the .4gi version.
