setenv <infile> <path name> m3edhdr [<infile>>] <and respond to the prompts>where infile is the logical name of the input file whose header attributes are to be edited. If infile is not present, the program will prompt the user for the input file logical name.
Before you run the program, you need to assign a logical name to the physical file names of both the input file and the report file (if any), according to Models-3 conventions, using the operation
"setenv <lname> <pname>"The program will prompt you for the logical name you have chosen for the input file, and then extensively for the options to choose; the prompts will have default responses which can be accepted by hitting <RETURN>. (Note that the default responses are in fact the values taken from the file itself, so that default behavior is not to change the attributes.)
Note that the set of edits which can be performed by one execution of M3EDHDR is quite complex, being dependent upon the variables and other structures in the file being analyzed. If you want to run this program in batch mode (i.e., from a script), the recommended way to develop the script is to run the program once interactively while noting the pattern of responses to prompts which generate the particular analysis you want. The pattern of responses then becomes either a command-input file which is redirected into the program's execution by the script, or becomes a "here-document" fed into the execution.
