File Input/Output Trace

Use the option GTFOPT=FIO to trace all file input and output operations including OPEN, CLOSE, GET, PUT, POINT, READ, WRITE etc. Alternatively, use the option GTFOPT=FOC, which traces file open and close operations only, to identify the location within an application where an OPEN or CLOSE is failing.

Here is the GTF trace file for a file input/output trace of the Assembler demo program pgasm04.mlc:

GTF option GTFFILE =D:\MFUSER\CONFIG\GTF.LOG                          
GTF option GTFOPT  =FIO                                               
GTF option GTFIMIN =00000000                                          
GTF option GTFIMAX =FFFFFFFF                                          
GTF option GTFAMIN =00000000
