The syntax listed in this chapter is accepted by your COBOL system purely for compatibility with version 2.0 of Ryan McFarland COBOL. Many features found in Ryan McFarland COBOL exist already in this COBOL implementation. Some of the compatibility syntax listed in this chapter is identical to standard COBOL syntax, but behaves differently if you set the RM Compiler directive when you submit your source code to your COBOL system. See the RM/COBOL Language Reference Manual version 2.0 for a full description of the Ryan McFarland syntax.
