Our #IBMChampion stars are reaching a series of amazing milestones! The program – and 6 of our original 12 IBM Champions – reaches 15 years old this year. Celebrate our long-serving Champions and start submitting nominations to join the 2023 cohort. ibm.co/3r0gGua pic.twitter.com/KqWttWBZyk

The Developers’ Corner: Bit shift, IBM i system variables via SQL and busy cursor

New feature in Visual LANSA EPC150050: BitShiftLeft and BitShiftRight

Bit shift is a bitwise operation where the order of several bits is moved, either to the left or right, to efficiently perform a mathematical operation. Bit shifts help with optimization in low-level programming because they require fewer calculations for the CPU than conventional math. Bit shifting operations may be declared explicitly by the programmer, or automatically by the compiler if it can identify that such an optimization is possible.
For example, consider the integer 23, represented with eight bits:
00010111
If we shift all the bits left one place, discard the leftmost bit, and insert a zero on the right, the result is the binary representation of 46:
00101110
This action is effectively the same as multiplying the number by two.
These intrinsics are available on LANSA Integer fields.

Show all IBM i System Variables via SQL script

The IBM i Access Client Solutions Windows tool has a Run SQL Script Database option.

If you run select * from qsys2.system_value_info you will get the results of all IBM i system variables in one overview:

How to show the busy cursor

A straightforward way to provide feedback if a process takes a while to complete is to show the Windows busy cursor. Event handling routines have a com_cursor() parameter which shows the hourglass cursor immediately, or after a delay of 1, 2, or 4 seconds.

If you test the source below in a Form, you can see how it behaves:

Com_Cursor parameter values are:

*DEFAULT
*DELAY_01
*DELAY_02
*DELAY_04
*IMMEDIATE
*NEVER

The Reasons Why Legacy IBM i Applications Hinder Your Workforce Potential

It is no secret that legacy applications are significant hurdles that impede the full realization of your personnel on both sides of the equation: developers and end-users. By Jose Caso, LANSA, an Idera Inc. Company In this case, I would like to write about the end-users as a homage for their hard dedication. They are the ones that struggle with IT inefficiencies and interact with applications every single working day with all their strengths and shortcomings. Although all may seem to be about users only, it is also about customer service. Front-line and service workers are the ones that deal the customer expectations and frustration. The heavy squeeze between customer satisfaction and business goals frequently doesn’t match reality.
