I'm guessing it means that to use the interface from COBOL one must... 1. Read the zlib documentation (https://zlib.net) to figure out how to call the library from C.
2. Cross-reference this with the documentation for the zEDC zlib implementation to determine which parameters are supported by zEDC. Now you know how to call zEDC from C. 3. Figure out how to make an *equivalent call* from COBOL, so that the C zlib API sees the same parameter linkage as it would from a C program. 4. Figure out how to link a ZFS library into an MVS load module.

Only the C language zlib library and functions are described. Tom provided the link to the book and on page 128 it states that the callable services "... are for use by any program coded in C, COBOL, Fortran, Pascal, or PL/I, and this information refers to programs written in these languages as high-level language (HLL) programs." -- Phoenix Software International Edward E.
