IBMi (AS400) fans only ' %DIFF BIF - How to add or subtract days from a date field %days(n)

#IBMiSample


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

 IBM Coding Forms Oh mom! No, not my sweet, sweet natural mom, but IBM, the mother of us RPG programmers. The adventure with IBM began way back in 1992 when my friend said to me: "They need smart guys at a software house in Cesena!" And thanks to my dear friend, I ended up there, amidst the hills, good wine, Piadina Romagnola, and fresh pasta! It was December, and the company was an IBM partner. They asked me to take a course followed by an exam at IBM in Bologna. If I passed the test, they would hire me. Boom! Just 20 days later, there I was, at work! I started tinkering with the legendary IBM S/36 - today considered an informatics relic, but I swear, back then, it was a powerful machine! The first program I wrote, believe it or not, was on paper provided by the ancient scribes of IBM. Yes, I handwrote a program on paper. It felt more like a grandma's recipe than the result of my hard-earned studies! The "boss" said: "It looks decent, but load it onto the

IBMi (AS400) fans only ' SQLCODE values: Dear readers, unleash your suggestions!

This RPG code uses a DOU loop to fetch data from a cursor named C1 until the SQLCODE is not equal to 0, indicating the end of the recordset. Inside the loop, it clears a data structure (RecordDsC1), fetches data into it, and then checks if the fetch was successful. If successful, it assigns values and writes to an output file. After the loop, it checks if the SQLCODE is not 100, indicating unexpected termination, and displays a warning message if needed. // Loop until SQLCODE is not equal to 0 dow sqlCode = 0 ;   // Clear the data structure RecordDsC1   clear RecordDsC1;   // Fetch data into RecordDsC1 using cursor C1   exec sql fetch C1 into :RecordDsC1;   // If fetch was successful (SQLCODE = 0)   if sqlcode = 0 ;     // Assign values and write to output     W1QUEU = rDsW1QUEU;     write W1SF1;   endif; enddo; // Check if SQLCODE is not 100 (indicating unexpected termination) if sqlCode <> 100;   // Build a warning message   wMsg='Warning: +    The selection has terminated
