Source line too long - The line of code is too long for the compiler to process. This can also occur if the file contains lines of source code that are not CR/LF delimited. Try breaking the line of code up into smaller logical lines with the use of line continuation characters, and ensure that the file is using the Win32 standard of CR/LF line delimiting. If you are using a 3rd-party editor, try opening the source code file in the PowerBASIC IDE and examine the lines where the error occurred -- merged lines here will be a good indication of invalid line delimiting.
