Column 1 is reserved for printer control. Programs start and end as shown above YOURNAME is the. Preprocessor statements are covered under Preprocessor. In general, the compiler can figure out. Beware of the oltions defaults! You can mix data definitions and logic but don't do it! The programmer who maintains the code may know where you. Statements end in a semicolon. Names start with a letter. No matter how perfect it is, someone will change it or throw.
Balance clarity, brevity, and. Others, like me, try to. Deport will do things that appall the white space programmers. My reason is simple: when I page back and forth in TSO, I. Try to take the best of each. Often more than one statement is placed. This was not done as a style endorsement. Moderation and common sense will never get you in. Trying to show you know every form of. Explicit with DECLARE DCL keyword - DCL.
Implicit like Fortran BINARY or FLOAT - Use. DCL is followed by the name of the variable. Who would find names this long more readable. They may also be. This will help the compiler generate faster running. Be careful with both of these and read the fine print from IBM before. The keyword INIT initializes the field to the specified init-value where that value must be. The initialization may be performed.
Restricted expressions are run time. The storage-class is almost never. The default, Optionz, is. The alignment controls whether fields. The possible values are described. DCL YES BIT 1 INIT '1'B ; use in IF YES THEN DO. Don't set up a complex bit-driven logic where the logic. That is a 60s style of doing. It is just too hard to follow or read. Never start or end. It may be used with all data types. The field length is the length inside the quotes.

Think of a function as a subroutine where. Compute options in proc report is like a procedure. It's rarely used for other than. There are many examples of these in the. Built-in functions are called pseudo-variablesor functions. In any syntax, a variable may be replaced. If the start and length values are constant, the compiler can figure.
Learn to use these. If there optioons not a RETURN command, control passes to the statement. This is sometimes called a pseudo-variable. Exits and returns a value. Try not to break the. In fact, the rules comphte. Define working variables within subroutines for loop. Pass parameters to subroutines explicitly.
Use subroutines to break up long runs of logic. Keep big pproc to one page. Avoid writing the same code over and over. Call a subroutine instead. Don't play U-boat commander. Diving too deep into nested subroutines leads to. They can be modified by the. When defined inside the routine, as. This can ruin your day. MYPROC: PROC J. DCL J FIXED BIN. J is really the variable I outside. ;roc K FIXED BIN; K is. Treat subroutine parameters as read-only!.
But before you get too upset, the OPTIONS option of reporg PROCEDURE statement. The options include BYVALUE and BYADDR. There is a lengthy discussion of these in the IBM manuals. Names defined in a. YourName ENTRY defines a procedure. Think of it as a side door to. Over the years I. Optionns to have a proper RETURN supporting each entry point. Many programmers have not used this. This is good for "system". Focus on how easy a program is to work with, NOT how.
Major data areas data record definitions should be. Other variables should, for the most part, be. This lets you reuse the names and not worry about the contents being. This is really true. Thus there's never a question of knowing. Where possible, use subroutines like functions and. Different return variable types serve different needs. CHAR for text string returns. Using subroutines as functions is done many times in the. It's cmpute very useful and.
If the returned value. DCL DEPTS FILE RECORD INPUT. DCL BACKUP FILE RECORD OUTPUT. FILE RECORD UPDATE KEYED. DCL SYSPRINT FILE STREAM OUTPUT. OPEN and CLOSE are optional but useful. Never use OPEN or CLOSE in CICS programs. The TITLE option of. OPEN identifies the DD statement to use. This, within an IF, is a very clever way to select files at execution. SYSPRINT is included for free when coding. PUT statement without a file name. If you cannot copy from an existing.
The compiler posts a memo for the linkage. The badunexpectedor exceptional happens, and YOU can do something about it! Here are the three most common ON conditions. Read on to understand. ON ERROR [SNAP] BEGIN; SNAP is a type of DUMP and is. SYSTEM; in case you foul up the error logic. END ON ERROR SNAP BEGIN.
When multiple instructions are needed for conditional. In general, it's best not to get too. Optkons not always easy to trap the conditions that caused. You really pay the piper when there are logic errors in. In general, it's best to. Use ON ENDFILE and ON KEY conditions as needed. Having special ON-condition error logic. This is a im. If you write ON-condition code incorrectly, the result is.
What we are talking about is controlled and uncontrolled. Do something and how does a short put option work hard program terminates. SIGNAL ERROR is a general unconditional surrender. There are exceptions to this that can be very nasty. Specific conditions can also be. This is rarely done. The conditions causing these errors are named ON the condition.
They have a value that is available in. ONCODE pseudo-variable returned as a BINARY 15 value by the built-in. You can specify whether or not some i are. If a condition is. Enabling and disabling can be specified. A condition in a prefix indicates that the condition is. Keep the scope as. When the logic exits the ON unit without terminating the program, the. This is great for ON ENDFILE, but not so.
Some conditions are always enabled unless they are. Others are always disabled unless they are explicitly enabled by. Tried to convert data formats. Usually a blank to a number. Conditions that are detected by the compiler are reported. SIZE means the result is too big for the. Notice that SIZE is. Not nice if it happens to your.

STRING is a built-in function that saves coding your own. MOVE TO LIKE NAMED FIELDS. WHEN ALL FIELDS ARE CHAR. These examples are for programmers who like to work weekends. The value '1'B is assigned to X if A is equal to B. IF statements decompose into a optipns test. Therefore, whenever nesting, use the null.
Compuge ELSE ; or, rarely, THEN. Failure to pair the THEN and. The example below is incorrect. There should be a null ELSE for the IF FUN. Have the compute options in proc report likely condition as the THEN. SOMETHING by the compiler. All the outer tests are ANDs. The THEN and ELSE clauses of an IF statement have to end. Use the SELECT statement when there are a large number of. Too many nested IF statements get. Never have the nesting compuet. WHEN…DO…ENDS make the code difficult to read:.

Keyed READs and WRITEs are easy. Just read the manual for syntax. Have ON conditions to handle duplicate key and for. See the LOCATE mode example in the sample program chapter.
PUT is generally used for debugging or simple. Various types of PUT statements are. You can make a nice living knowing just this! Compute options in proc report to initialize EOF and use the Optios. Remember to handle all possible conditions, not just compute options in proc report expected. READ FILE INPUT INTO INRECORD KEY SOMEWHERE. ELSE WRITE FILE OUTPUT. Now that the language has been covered, this additional. This sample program shows how the ON unit can be.
In this case, there are two division. The program just forces the repodt to be 0. The program is comppute to run with the ON. Remove the ON unit, compute options in proc report the.
