RE: Indicator variable

[Dave Boettcher <DBoettch@xxxxxxxxxxxxxxxx>]

Not sure what syntax you are looking for, but here is a start

for null indicators:
D*  AddrFldsNull     DS                  
D NLad_phone      S              5I 0    

For usage in the calcs:
C                   if        nlad_phone >= *zero                       
C                   Eval      %subst(AlphaCvt:13:3)                     
C                               =  %trim(%subst(A_ad_phone:1:3))

I have a program that uses SQL and gives a message in the joblog every 
time it tryes to read a NULL.  

This is the SQL:
____________________________________________________________________________
____
c/exec sql
c+ select trim(name) || ' ' || lname into :nombre
c+   from salary/emple_ncl where usuario = ucase( :id)
c/end-exec
____________________________________________________________________________
_______
and this is the message:
____________________________________________________________________________

I understand that I need to specify an indicator variable, but I could 
not find how to specify the indicator.  do you remember the sintax? Thanks.
