The INCLUDE statement allows the statements in the specified file to be treated as if they were being included in a program in place of the INCLUDE statement itself. This simplifies the maintenance of common-block declarations and is an important tool in keeping code well organized. In CIFtbx, the INCLUDE statement is used to bring the statements in the files ciftbx.cmn and ciftbx.sys into programs where they are needed, and to simplify ciftbx.cmn and ciftbx.sys by using INCLUDEs of the files ciftbx.cmv and ciftbx.cmf. The file ciftbx.cmv contains the definitions of the essential CIFtbx data structures as common blocks, for inclusion in both ciftbx.cmn for user applications and in ciftbx.sys for the CIFtbx library routines themselves. Most compilers handle the INCLUDE statement, but, if necessary, a user may replace any or all of the INCLUDE statements with the contents of the indicated file. For example, the only non-comments in ciftbx.cmn are![[Scheme scheme10]](/schemes/Gach5o4scheme10.gif)
This means that the file ciftbx.cmn could be replaced by a concatenation of the two files ciftbx.cmv and ciftbx.cmf.
