Re: Treating a character as a logical -- RPG400-L

1)  Can you really put an = right after an eval to change it's function?
Normally I don't use eval.  Rather redundant on free format code.

2)  You're still doing a compare.  If this, then turn the logical off or
on.  I was hoping to avoid the additional compare.

Before we had *on or *off in the language we used '0' for off and '1' for
on.  Some of us created variables named ON and OFF to be more documenting.
Then IBM added *ON and *OFF.
Based on this remembrance of history,  I should be able to set my logical
variable based on the character variable.  Now I just have to report yet
another bug that the precompiler doesn't support logical variables in sql
statements.

Gee, if IBM added reserved words for *on and *off, what would it take to
get reserved words for all the status codes?  Or at least a nice /include?

Well, what I think that you can do is compare that field to a value and
depending on the result, then you can turn a logical variable *on or *off.
What
I have done in the past is like this example:

On the Data Definition:
DCycle_Cnt_Flg    S              1n

On Calculations:
eval=Cycle_Cnt_Flg = *Off
If CCFLG = '1'
eval=Cycle_Cnt_Flg = *On
Endif

And later in the calcs:
If Cycle_Cnt_Flg
Processing...
Endif

Can I do the following with a variable defined as 1A?  The possible values
of this variable are *blank and '1'.
If found;
...
EndIf;

Or do I have to do:
If (found=*on);

SELECT MYVAR into :found FROM ROB/TESTSQL WHERE EXISTS (
select DBNAME from qsys2/syscolumns
where dbname=?
 and TBNAME between ? and ?
 and NAME between  ? and ?)
