Patrick,
The below program can serve your requirement.
=================================================================
1. D dtads ds
2. Dsubfld 6s 0
3. C *dtaara define PROCYR 6 0
4. C *lock in procyr
5. C move procyr dtads
6. * create a character representation of the data area
7. C movel subfld charfld 6
8. C charfld dsply
9. C move dtads procyr
10. C out procyr
11. C eval *inlr = *on
12. C return
=================================================================
I do not know, why you are moving to data structure with one sub
field. If you want to use with single field numeric data area to a character
field in your program you need NOT to have DS at all. In this case please
remove the inline code above by line 1,2 and 7. Change line 5 as
5. C movel procyr charfld 6
Change line 9 as
9. C move charfld procyr
that 's it.
If you want to access data area data structure, it is allowed only on *LDA
type.
UDS data structure is explicitly based on the *LDA using the DTAARA
keyword. Since it is a data area data structure, it is read in during
initialization and written out during termination. It can also be handled
using IN and OUT operations, since the DTAARA keyword was used.
Generally, UDS is used as
D uds
Dsubfld 1 600A
If you want to use DTAARA keyword, you may need not give data structure name
also.
D LDADS UDS DTAARA(*LDA)
Dsubfld 1 600A
........
C IN LDADS
........
C OUT LDADS
Please remember, the *LDA is always *CHAR type.
Regards,
Ramana

Subject: data area question
Folks, I need some guidance. I very rarely use data areas to transfer
information, but in this case I must capture some data that is stored there.
Whenever I run this program I get an error message telling me that my data
area type or length does not match my program data area.
Any tips would be appreciated.
Thanks in advance,
Patrick
Code (V4R5):
D period uds dtaara(PROCYR)
D cmonth 6s 0
D month s 6
* create a character representation of the data area
C move cmonth month
*
C eval *inlr = *on
C return
Data area definition:
Display Data Area
System:
Data area . . . . . . . : PROCYR
Library . . . . . . . : FILLIB
Type . . . . . . . . . : *DEC
Length . . . . . . . . : 6 0
Text . . . . . . . . . : Processing Year and Month

Message . . . . : Data area PROCYR type or length does not match program
data area.
Cause . . . . . : Data area PROCYR was defined in the RPG procedure to be
of
type *CHAR and length 6. The actual data area XYZLIB/PROCYR is of type
*DEC
and length (6 0). If a *LGL data area is expected, a data area of type
*CHAR
and length 1 is also allowed.
Recovery . . . : Correct the type or length of the data area, or change
the
library list so the correct data area will be found.
