Re: Time Constant Errors

Right. DATFMT, and presumably TIMFMT do not actually exist in memory in the
format we specify. I am aware of that. But when I say internal, I mean what
the program sees, and when I say external, I mean what the user sees. The
program does see things in DATFMT and TIMFMT format. Constants must be
specified in these formats. And DATFMT and TIMFMT do limit what the field
can hold. That is more true for DATFMT than TIMFMT. Specifically you cannot
put d'0001-01-01' into a date field defined with DATFMT(*MDY). I really
don't care much about how IBM i stores it below the MI. There is no easy
way for me to get to that. Even in debug when I am looking at a memory dump
I see the data in DATFMT or TIMFMT format. But since I am using *ISO for
dates, I want to, and do, use *ISO for times as well.

[WDSCI-L] Time Constant Errors

RDi - 9.6.0.1
IBM i - 7.1

I have the following code

**free
ctl-opt Option(*SrcStmt : *NoDebugIo: *NoUnref)
DatFmt(*ISO) TimFmt(*ISO)
DftActGrp(*No) ActGrp(*New)
BndDir('JCS')
Main(JCUPDFLCYR);

...

dcl-s RunTime Time Inz(t'02.03.00');

. . .
. . .
. . .

If I change my default time format to *HMS, and the time literal to
t'02:03:00', then RDi is happy (it also compiles properly). But I prefer

to

keep my dates and times in *ISO format internally.

I would agree LPEX error checking should be accurate. But just to be clear
. . .

I believe when you specify a time field (or any timedate field), the
system does not store it internally as *ISO, *HMS, or any other string
representation. When the field is 'externalized', it converts the value to
whatever format you've specified. So you can input a field as *HMS, and
move it to *ISO (or any other desired format) and the system handles the
conversion for you.

At least this is true when DB2 (or Db2) stores the data. I believe the
same holds true in RPG and COBOL.
