Looping on the CLP AS400 uses the LABEL function and IF function. 1 brought us the DOFOR. In this session we will learn about the following things:-1. 2. To do that you need to code the loop in one CL program and call a second CL program to handle the file. Explore IBM Documentation for comprehensive resources and information on various IBM products and services. I have a AS400 table that contains multiple rows per person. LEAVE opcode example is given below. IBM Documentation provides access to various resources and information for developers and users. DO opcode example is given below. So just for my reference here is an example of the exact same code in RPG3, RPG400 and RPGLE (or RPG5 as its sometimes called). Example of DOWHILE loop in CL program in English.

For more s I will discuss about using looping on AS400. These CL variables were automatically declared in the program when the CL source program was compiled and a Declare File (DCLF) command was processed as part . If in other programming we can use the for, do-while or other functions. It is time to do the same in your CL. The DOWHILE command is used to state a condition that, if true, specifies a command or group of commands in the program or procedure to run.

CL does DO Subroutines I cannot think of RPG without subroutines. While the SQL statements cannot display data directly to the screen, the same restriction does not apply to the scripted CL commands. Compile and run the program. Once opened, you can't change to a different file by running OVRDBF and then another RCVF. Line 7: In CL I use the SNDRCVF command to send the display file's contents, and then receive the data from it when Enter is pressed.
