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

       file1 file2 file3

DESCRIPTION

       combines  two  files  that are revisions of a single original file.  The original file is file2, and the revised files are file1 and file3.
       identifies all changes that lead from file2 to file3 and from file2 to file1, then deposits the merged text into file1.	If the	option	is
       used, the result goes to standard output instead of file1.

       An  overlap  occurs  if both file1 and file3 have changes in the same place.  prints how many overlaps occurred, and includes both alterna-
       tives in the result.  The alternatives are delimited as follows:

	      lines in file1
	      lines in file3

       If there are overlaps, edit the result in file1 and delete one of the alternatives.

       This command is particularly useful for revision control, especially if file1 and file3 are the ends of two branches that have file2  as  a
       common ancestor.

EXAMPLES

       A typical use for is as follows:

	      1.   To  merge  an  RCS branch into the trunk, first check out the three different versions from RCS (see co(1)) and rename them for
		   their revision numbers: 5.2, 5.11, and 5.2.3.3.  File 5.2.3.3 is the end of an RCS branch that split off the trunk at file 5.2.

	      2.   For this example, assume file 5.11 is the latest version on the trunk, and is also a revision  of  the  "original"  file,  5.2.
		   Merge the branch into the trunk with the command:

	      3.   File  5.11  now  contains  all  changes  made on the branch and the trunk, and has markings in the file to show all overlapping
		   changes.

	      4.   Edit file 5.11 to correct the overlaps, then use the command to check the file back in (see ci(1)).
