TRUNCATE function - is it documented?

I cannot find any documentation for the TRUNCATE function in the 5.3.2 docs. Is it documented in a newer release?

It appears that it only works in Dialogue Manager, I tried it in a DEFINE and got

(FOC263) EXTERNAL FUNCTION OR LOAD MODULE NOT FOUND: TRUNCATE

I realize it may not make sense to use it in a DEFINE.

I'm on version 536 and the TRUNCATE function does not exist. I receive the same error message you are getting.

This is how we do it:

DEFINE FILE CAR
TAX/D12.4 = .08125;
SALESTAX/D12.4 =
TRUNC_SALESTAX/D12.2 = EDIT(STRIP(14,SUBSTR(14, FTOA(SALESTAX*100, '(D12.2)', 'A14'), 1,
(POSIT(FTOA(SALESTAX*100, '(D12.2)', 'A14'), 14, '.', 1, 'I2'))-1, 14, 'A14'), ',', 'A14'))/100;
DRIVEOUT/D12.2 = TRUNCATE(RETAIL_COST * TAX);
END
-*
TABLE FILE CAR
PRINT
RETAIL_COST
TAX
SALESTAX
TRUNC_SALESTAX
DRIVEOUT
ON TABLE PCHOLD FORMAT EXL2K
END

I'm sure there is a shorter way but this is the one I came up with on the fly.

Ok, I must be sleeping. I don't know what happened on the first post.

The second was where I tried the truncate function to see what the error message was I received.

If you take out

DRIVEOUT/D12.2 = TRUNCATE(RETAIL_COST * TAX);

the query will run.

Sorry for all the confusion.

I think I'll go take a nap now Music

quote:
(FOC03665) Error loading external function 'TRUNCATE'This function can only be used in Dialogue Manager commands that support function calls, such as ‑SET and ‑IF commands. It cannot be used in ‑TYPE or ‑CRTFORM commands or in arguments passed to stored procedures.

You can't use it in a define statement. OR maybe you can based on Glenda's test but that's a numeric calculation she's doing so who knows.

Leah,

Your are correct. I don't use the TRUNCATE function. Instead, I came wrote a numerica calculation to use in place of the TRUNCATE function.

although it would take me more than a long nap to understand Glenda's DEFINE's... ( we need a smiley for head spinning out of control)
if what you want to do is essentially ROUNDDOWN an end result, then you can write your own TRUNCATE function and stick it in your edasprof.
eg:

-SET &ECHO = ALL ;
 

DEFINE FILE CAR
SALESTAX/D9.4 = .0825 ;
TAX/D9.4=SALES * SALESTAX;
temp1/I9=( TAX * 100) ;
rightanswer/P9.2=temp1/100;
wronganswer/P9.2= TAX;
END

TABLE FILE CAR 
PRINT SALES SALESTAX TAX  temp1 rightanswer wronganswer
COMPUTE OOPS/D9.2S=rightanswer - wronganswer;
ON TABLE HOLD AS MYTAB FORMAT HTMTABLE
END
-RUN
-STEP2
DEFINE FUNCTION F_TRUNC(number/D9.4)
temp1/I9= number * 100 ;
F_TRUNC/P9.2= temp1/100;
END
DEFINE FILE CAR
SALESTAX/D9.4 = .0825 ;
rightanswer/P9.2=F_TRUNC(SALES * SALESTAX);

END
TABLE FILE CAR 
PRINT SALES SALESTAX     rightanswer  
ON TABLE HOLD AS MYTAB1 FORMAT HTMTABLE
 END
-RUN
-HTMLFORM BEGIN
<TABLE><TR><TD>
!IBI.FIL.MYTAB;
<TD>!IBI.FIL.MYTAB1;
</TABLE>
-HTMLFORM END

Of course this is silly to ask now, Francis, but are truncating numbers or character strings?

I was truncating character strings. Since I used TRUNCATE to concatenate First Name and Last Name Dialogue Manager variables, I thought I would modify the technique I use in a COMPUTE or DEFINE to use TRUNCATE instead of hard concatenation with a blank in between. But TRUNCATE only works in Dialogue Manager.

Cheers.
