*INU1 is being assigned the value of the logical comparison, which is either true ('1') or false ('0').


This code snippet might show you better what is happening...

D INDIC01         S              1A   INZ('1')
D INDIC02         S              1A   INZ('1')
D INDIC03         S              1A   INZ('0')

C                   EVAL      *INU1 = (INDIC01 = INDIC02)
C     '*INU1'       DSPLY                   *INU1

C                   EVAL      *INU1 = (INDIC01 = INDIC03)
C     '*INU1'       DSPLY                   *INU1

C                   EVAL      *INLR = *ON

Hmm, this is what I thought it was, but I just entered this code into a
source member I use for testing snippets of code:

  field1test = field2test = '1';
  dsply field1test;
  dsply field2test;

the first dsply returned '0'
the second one returned a blank

both field1test and field2test are defined as 1 byte alpha fields.

Anyone else care to chime in?


Thanks,

Mark

It's setting two fields to '1' or *ON at once. Although, I didn't know this
was valid RPG syntax. Learn something new every day.

I just encountered a line of code I have never seen before and can't figure out exactly what it is doing.



C                   EVAL      *INU1 = DETSTY = '1'



The field DETSTY is a 1 char field described in a DSPF. What is the
purpose of an Eval statement like this?



Thanks,

Jeff
