IBM i (AS400) fans only - tips and tricks to start RPGfree programming - simple examples of RPG Free

#IBMiSample In this example CHKDS4.RPGLE detects the screen setting. As an example I propose a CLP that calls PGM1 if the setting of 80 columns is detected, or calls PGM2 if the setting of 132 columns is detected.

#IBMiSample Subfile window with mouse selection - DoubleLeftClick - MOUBTN(*ULD CA04) This example uses DoubleLeftClick MOUBTN(*ULD CA04) to select a subfile row. Please note: the mouse works with "Personal Communications iSeries Access" and does not work with a simple 5250 emulator (for example Mocha TN5250 does not detect the mouse). If you don't have "Personal Communications iSeries Access" it doesn't matter, the mouse doesn't work but the function keys work as usual. First of all look at this post and compile and populate CLANA00F to use this example. Don't forget to set the screen to 132 columns!    This is the display file: CL01SFV.DSPF       **************************************************************       *  CLANA01L Subfile with select option       **************************************************************                                             DSPSIZ(27 132 *DS4)                                             INDARA              

#IBMiSample The check digit is the last digit of each barcode and is used to verify the correctness of the GS1 codes (formerly EAN codes). This program calculates the check digit of an EAN-13 barcode: EAN13C.RPGLE **FREE   ctl-opt option(*nodebugio:*srcstmt:*nounref) dftactgrp(*no);   // ****************************************************************   // * Autore.......: ALDO SUCCI                                    *   // * Descrizione..: CALCOLO DEL CHECK DIGIT X EAN13               *   // * Data.........: 15/06/09                                      *   // ****************************************************************   // *                                                              *   // * Parametri in input:PARAM (12 cifre EAN)                      *   // *             output:WDIGIT (13° carattere Check digit)        *   // *                                                              *   // *                                                              *   // * il caratt

#IBMiSample We can use %DAYS to add or subtract to a date. Hier is an example:

#IBMiSample The ACTIVE_JOB_INFO table function returns one row for every active job.  You can use it to get the same information as the WRKACTJOB command in an alternate mode. Look at the following examples: a. List all jobs of  user VDOTEST SELECT JOB_NAME, SUBSYSTEM, SUBSY00001, AUTHO00001, JOB_TYPE, FUNCT00001, FUNCTION, JOB_STATUS,  MEMOR00001                 FROM TABLE(ACTIVE_JOB_INFO())                                 WHERE JOB_NAME LIKE '%VDOTEST%'                               b. List all jobs of  subsystem QBATCH SELECT JOB_NAME, AUTHORIZATION_NAME, ELAPSED_TOTAL_DISK_IO_COUNT, ELAPSED_CPU_PERCENTAGE                                            FROM TABLE(QSYS2.ACTIVE_JOB_INFO(                                 SUBSYSTEM_LIST_FILTER => 'QBATCH')) A                             ORDER BY ELAPSED_TOTAL_DISK_IO_COUNT DESC                         c. List all jobs temporary storage SELECT JOB_NAME, AUTHORIZATION_NAME, TEMPORARY_STORAGE,      SQL_STATEMENT_TEXT
