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

#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       **************************************************************                             ...

#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 Typically we have a table and we need to perform read, write, update operations. This simple program is an example of how. First of all look at  this post  and compile and populate these files to use this example.

#IBMiSample First of all please refer to  this post  to compile and populate the necessary files for this example. Then, compile the following sources: OT08SF.DSPF for the display file and OT08SF.SQLRPGLE for the RPGLE program. Display File: OT08SFV.DSPF                                             CHGINPDFT(CS UL HI)                                             INDARA                                             CA03(03 'F3=EXIT')                                             REF(OTORD00F)       *-------------------------------------...
