How to use IF condition in CL program?
The If (IF) command is used to state a condition that, if true, specifies a statement or group of statements in the program or procedure to be run. The Else (ELSE) command can be used with the IF command to specify a statement or group of statements to be run if the condition expressed by the IF command is false.
Does CL do until loop?
The Do Until (DOUNTIL) command processes a group of CL commands one or more times. The group of commands is defined as those commands between the DOUNTIL and the matching End Do (ENDDO) command. After the group of commands is processed, the stated condition is evaluated.
What is the purpose of the ELSE command?
The Else (ELSE) command is a way of specifying alternative processing if the condition on the associated If (IF) command is false.
Do while loops as400?
Ü DOW (Do While) The EndDo represents the end of DoW block. The RPGLE statements inside these opcodes are iterated till the condition remains true. The looping condition is specified as factor2 of the DoW opcode. The looping condition is checked at the beginning before any iteration begins.
What is the difference between ITER and leave in as400?
The ITER operation takes the control to ENDDO, ENDFOR while LEAVE transfers control to the statement following the ENDDO or ENDFOR operation.
What is a else if statement?
Alternatively referred to as elsif, else if is a conditional statement performed after an if statement that, if true, performs a function.
What are the difference between Dow and Dou in as400?
DOU processes a loop UNTIL a condition is met. DOW processes a loop WHILE a condition is met. DOU will process the loop and then check if it should process again, thus it will always execute the loop once and check afterwards, even if the condition was true before the loop ever started.
Do commands as400?
The Do-EndDo loop is used when we have to iterate over a block of statements for specific number (say 10, 20 100) of times. The do loop takes arguments as below: The Starting Counter, The maximum value and the index value. We can specify any of the above values as variables.
What does ITER do in Rpgle?
The ITER operation transfers control from within a do group to the ENDDO statement of the do group. It can be used in DO, DOUxx, and DOWxx loops to transfer control immediately to a loop ENDDO statement. It causes the next iteration of the loop to be executed immediately.
What is DO statement in C?
ANSWER. The C do while statement creates a structured loop that executes as long as a specified condition is true at the end of each pass through the loop.
What is if statement in C?
C has the following conditional statements: Use if to specify a block of code to be executed, if a specified condition is true. Use else to specify a block of code to be executed, if the same condition is false. Use else if to specify a new condition to test, if the first condition is false.
What is the difference between Dow and Dou?
What is the use of if command in C?
The IF command is valid only in a CL program or ILE CL procedure. Up to ten levels of nested IF and ELSE commands are allowed. Specifies the logical expression that is evaluated to determine a condition in the program and what is done next.
What happens if a false condition exists in a CL program?
If a false condition exists (ESTW contains a value of 0), the commands in group A are bypassed, the commands in Group B are processed, then control passes to the commands in Group C. The IF command is valid only in a CL program or ILE CL procedure.
Do you have to compile CL source statements?
As with other kinds of procedures, you must enter, compile, and bind CL source statements before you can run the program or procedure. When you enter CL commands individually (from the Command Entry display, for instance, or as individual commands in an input stream), each command is separately processed.
What is the use of else and if command in Linux?
The If (IF) command is used to state a condition that, if true, specifies a statement or group of statements in the program or procedure to be run.
