What Is COB2SAS?

COB2SAS is a free sample program that can assist you with converting COBOL data description entries (also known as FDs, copybooks, or copylibs) into equivalent SAS^® language INPUT and LABEL statements. COB2SAS reads, as its input, your COBOL program (or copybook). It parses the COBOL program, searching for FILE DESCRIPTOR sections. When COB2SAS finds a FILE DESCRIPTOR section, it parses this section to produce an equivalent SAS INPUT statement. A SAS LABEL statement is also produced to associate the SAS variable names with the COBOL data names. These INPUT and LABEL statements then can be used in a SAS program to read the file in which the FILE DESCRIPTOR section was pointing. A SAS data library is also produced that contains all of the information gathered about the copybook.

COB2SAS is written in the SAS language and executes on MVS, CMS, UNIX, and Windows platforms.

The SAS variable names that are produced will be up to 30 characters long. By default, the SAS INPUT and LABEL statements are written to an external file that is referred to by the OUTSAS fileref. By default, the information gathered by COB2SAS is written to a permanent SAS data library that is referenced by the PERM libref.

Conclusion

COB2SAS is a tool that that can be used to assist in converting COBOL copybook to SAS INPUT statements. There are some things that COB2SAS cannot fully handle and requires additional work so SAS can properly load the data files created by your COBOL program. Refer to the FAQ document for information about some of the common problems.
