IBM i fans only - tips and tricks to start RPG free format programming with simple examples

#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                                            F...

#IBMiSample INDARA (Indicator Area) keyword for ICF files workstn indds indicator data structure INDARA is used to put the field option indicators and function(response) key indicators in a separate area of memory called indicator area. By using this keyword, we can make indicator data structure in our program to give the customized name to indicators defined in the display file. Hence, it makes the program more readable and easy to understand. Step 1. indicate INDARA  keyword in your Display File Step 2. indicate INDDS in your RPG workstation file declaration dcl-f PKLTSFV workstn indds(Dspf) sfile(SFL1 : SF1NUM); Step 3. declare the  indicator area        dcl-ds Dspf qualified ;          Exit            ind pos(03) inz(*off);          SflClr          ind pos(50) inz(*off);          DspAtrRI        ind p...

#IBMiSample I'm tired of one-line messages. Too short. The average user needs clear and comprehensive messages. Then I need a large enough window to display a clear and complete message . Why not use a SUBFILE? A SUBFILE program can handle a list of many lines, a clear and complete message is just a list of many text lines! Here's how I did it I need a table that contains the messages.                           --                                                  --  RUNSQLSTM SRCFILE(VDOTEST1/QSOURCE) SRCMBR(W03AM00F) --                                                  CREATE TABLE VDOTEST1/W03AM00F (                  ...

#IBMiSample The Run SQL Statements (RUNSQLSTM) command processes a source file of Structure Query Language (SQL) statements. let's have an example: Create a source member AS52A00F into library VDOTEST1/QSQLSRC. VDOTEST1 is MyLibrary. Use your library name. AS52A00F.SQL
