Here is an example, written on the assumption your programs create no files.

Code:
# Named Makefile, in the current directory
file4:file3
        ./sqr.ksh axpyi035_sf axpyi035_sf.par $1 $2 XHRPPYA4;
        touch file4
file3:file2
        ./sqr.ksh axbni061 axbni061.par $1 $2 XHRPBYOX;
        touch file3
file2:file1
        ./sqr.ksh axbni062 axbni062.par $1 $2 XHRPBYOW;
        touch file2
file1:
        # Code to run program1 here
        # Leave the 'touch', Make needs it to track
        ./sqr.ksh axhri051_sf axhri051_sf.par $1 $2 XHRPPYOV;
        touch file1

clean:
        rm -f file1 file2 file3 file4

When you run make, it will attempt to create file1 through file5 in that order, by running the commands you tell it to. If there is an error, it will detect the nonzero return code and stop in the middle. Next time you run it, it will remember where it left off by what file1...file5 files have and haven't been created.

Run 'make clean' to remove the files and start over from the beginning.

NOte that the eight leading spaces are actually tabs and must be tabs for make to work.

merge

MERGE(1)						      General Commands Manual							  MERGE(1)

NAME

       merge - three-way file merge

SYNOPSIS

       merge [ options ] file1 file2 file3

DESCRIPTION

       merge  incorporates all changes that lead from file2 to file3 into file1.  The result ordinarily goes into file1.  merge is useful for com-
       bining separate changes to an original.	Suppose file2 is the original, and both file1 and file3 are modifications of  file2.   Then  merge
       combines both changes.

       A  conflict  occurs  if	both  file1 and file3 have changes in a common segment of lines.  If a conflict is found, merge normally outputs a
       warning and brackets the conflict with and lines.  A typical conflict will look like this:

	       file A
	      lines in file A
	      =======
	      lines in file B
	       file B

       If there are conflicts, the user should edit the result and delete one of the alternatives.

OPTIONS

       -A     Output conflicts using the -A style of diff3(1), if supported by diff3.  This merges all changes leading from file2  to  file3  into
	      file1, and generates the most verbose output.

       -E, -e These  options  specify conflict styles that generate less information than -A.  See diff3(1) for details.  The default is -E.  With
	      -e, merge does not warn about conflicts.

       -L label
	      This option may be given up to three times, and specifies labels to be used in place of the corresponding  file  names  in  conflict
	      reports.	 That  is, merge -L x -L y -L z a b c generates output that looks like it came from files x, y and z instead of from files
	      a, b and c.

       -p     Send results to standard output instead of overwriting file1.

       -q     Quiet; do not warn about conflicts.

       -V     Print version number.

DIAGNOSTICS

       Exit status is 0 for no conflicts, 1 for some conflicts, 2 for trouble.

BUGS

       It normally does not make sense to merge binary files as if they were text, but merge tries to do it anyway.
