Hi All,

I used OUTRAP to capture the output but the OUTRAP is not capturing the data

/* REXX */
SAY "ENTER HLQ"
PARSE UPPER PULL DSN1
ADDRESS TSO
X = OUTTRAP('VAR.')
"HLIST DSNAME('"DSN1"') BCDS"
SAY 'THE NO OF LINES TRAPPED IS' VAR.0
LINES = VAR.0 + 1
DO I=LINES TO VAR.0
SAY VAR.I
END
X = OUTTRAP('OFF')
IF RC > 0 THEN
SAY 'YOUR O/P IS WRITTEN'
ELSE
SAY 'SORRY SOME ERROR HAS OCCURED' RC
EXIT

Please let me knwo if corrections required or cant we capture the data of HLIST commands using OUTTRAP?

Hi Robert,

Really thanks for ur great information..!!!!

here I am creating the file with my user id (HLQ) only. So I canged code as you have mentioned. I am not getting the dataset allocation error.

However I the dataset is empty. It doesnot have the required data.

Please see the code belwo and correct me

Select all

/* REXX */
DUH_USER = USERID()
DSN=DUH_USER'.ITEMS.LIST'
Y = DSNCKC(DSN)
ADDRESS TSO
"ALLOC F(OUT) DA('"DSN"') NEW TRACKS SPA(60 45) " ,
" LRECL(80) RECFM(F B) BLKSIZE(9040) DSORG(PS)"
IF RC > 0 THEN
DO
SAY 'ALLOCATION FAILED RC=:' RC
ADDRESS TSO 'FREE F(OUT)'
EXIT
END
SAY "ENTER HLQ"
PARSE UPPER PULL DSN1
ADDRESS TSO
"HLIST DSNAME('"DSN1"') BCDS ODS(ND2659A.DSN)"
SAY ND2659A.DSN
EXIT
DSNCKC: PROCEDURE
PARSE ARG DSN
DSN = "'"DSN"'"
ADDRESS TSO
X = SYSDSN(DSN)
IF X ¬= 'OK' THEN RETURN DSN
ELSE
DO
ADDRESS TSO DELETE DSN
IF RC = 0 THEN SAY 'DELETED'
ELSE SAY 'NOT DELETED'
RETURN DSN
END

Please correct me !!!!!!!!!!!!!!!!!!!!!!!

Select all

LINES = VAR.0 + 1
DO I=LINES TO VAR.0

say var.0 is 20. the first line above sets lines to 21. You then try to do i = 21 to 20. No wonder you appear to have no output - your loop is never entered.as your TO value has to be greater than your FROM value unless you are doing BY -1

Hi ,

I changed the code but the OUTRAP is not capturing the output

Select all

ADDRESS TSO
X = OUTTRAP('VAR.')
"HLIST DSNAME('"DSN1"') BCDS"
SAY 'THE NO OF LINES TRAPPED IS' VAR.0
LINES = VAR.0 + 1
DO I=1 TO LINES
SAY 'IN LOOP'
SAY I
SAY VAR.I
I = I + 1
END
X = OUTTRAP('OFF')

Please let me know if we have any alternative?

I have tried using the ODS(a.dsn name)

where is 'a' is my user id. But still the RACF accees error is hown.

I need the data i am getting when i execute the HLIST command?

Read about the OUTDATASET parameter of the LIST command in the fine manual. Incidentally, unless you've changed the default environment earlier, ADDRESS TSO is a wombat; if you have changed, you probably shouldn't have.

What does var.0 show when you trace it? Why are you looping through MORE lines than you have (var.0 + 1)? Why are you incrementing I twice - once in the DO statement and once explicitly in I = I + 1? why are you not doing it simply:

Select all

Do i = 1 to var.0
Say var.i
End

And what is

accees error is hown

? I presume 'accees' is a typo for 'access' but 'hown'? If you mean 'thrown' you are wrong - things are not 'thrown' on a mainframe: they are displayed, subbed, issued whatever but never 'thrown'.

but 'hown'

Shown?

Ah - yes. The missing 'S' syndrome. I had one in that post as well - corrected now.
