The named constant must become described before the definition statement.Extra free-form support for the RPG vocabulary and inserted SQL precompiler had been offered for L, F, G, and P specs.Free-form G specs had been previously supported, and now all RPG specs have got free-form assistance except I and O specs.
It allows developers who are familiar with other languages such as Microsoft Visual Fundamental, Java, and PHP to become trained even more quickly in RPG ánd with lower cost. The brand-new syntax also makes programming less difficult for present RPG programmers. As such, the free-form syntax is helpful for both existing RPG programmers and new RPG programmers. Desk 1 includes a long symbol title definition in fixed type and free of charge form. D name Beds 10A DCL-S thisisalong name CHAR(10); or DCL-S thisisalong. Illustration 1 illustrates the compiler diréctives within a announcement statement. ![]() Multiple control statements are allowed and free-form control statements can end up being intermixed with fixed-form L specs. A free-form data definition statement begins with DCL-, and is definitely followed by the data item name (which can end up being N if the data item is unnamed), then by an optional data kind, and after that by zero or more keywords, and finally finishes with a semicolon. There are several types of assertion claims: named constants, stand-alone areas, data structures, process prototypes, and process interfaces. Fixed-form keywords that alter a data type, such as VARYlNG, DATFMT, TIMFMT, PR0CPTR, and CLASS, are merged with the information kind keywords. ![]() Instead of defining a field as an object and incorporating the CLASS keyword, the class is chosen as the paraméter to the OBJECT keyword. Instead of understanding a field as time and adding the DATFMT keyword, the day format is definitely chosen as the paraméter to the Time keyword. Instead of defining a industry as a pointer and including the PROCPTR keyword, PROC is certainly chosen as a paraméter to the Tip keyword. Instead of defining a industry as time and incorporating the TIMFMT keyword, the time format can be stipulated as the paraméter to the Period keyword. Instead of major a industry as alphanumericUCS-2visual and incorporating the VARYING keyword, the field is described using the VARCHAR VARUCS2 VARGRAPH keyword. This fresh rule also can be applied to fixed-form N and G specifications. If a information type keyword is given, it must be the very first keyword. Example 6 demonstrates many stand-alone industry declarations. An optional second parameter can become described on the Want keyword to do a size adjustment. Example 7 demonstrates stand-alone decIarations with the Want keyword. ![]()
