To examine portability in CTRON, general program management software from CTRON extended OSs was ported across various architectures. To allow portability, various modifications to the target system and to incompatible interfaces were made. The modifications requiring the most time were to the general program management software in the source system and to the load module format in the target system. There were two portings to different architectures: in the first case, porting was achieved with modification of less than 10% of the source system's code; in the second case, less than 5% modification was needed. The authors compare the two projects, and consider the results of the two porting attempts. They examine possible areas where the CTRON specifications can be enhanced to increase the portability between Extended OSs
