I want to use the value of the number of rows that are in a hold file later on in another query in the same .fex. Is this doable?

Thanks Trudy

Yep, it's possible.

I have an example I had to create that used a SUM, but the concept is the same just using COUNT instead.

 
-*get the sum of the records out of hold into hold
TABLE FILE HOLDEVERYTHINGDIST
SUM
     HOLDEVERYTHINGDIST.SEG01.CLOSED_ALL_REQUESTS AS 'CLREQS'
ON TABLE NOTOTAL
ON TABLE HOLD AS HOLDCLOSEDTOTALS FORMAT FOCUS
END

-*set the amper variable using READFILE
-DEFAULTH &CLREQS = 0
-RUN
-READFILE HOLDCLOSEDTOTALS
-TYPE CLREQS IS &CLREQS


Once you have that amper value set then you can use it at your leisure after that. I will note it is imperative that the column in the hold file and the amper variable carry the same EXACT name. Otherwise it won't work.

Hi Trudy,

Here's an example using the CAR file. It creates 2 hold files and stores the record count in DM variables that can be used later in the fex.

-*
TABLE FILE CAR
PRINT CAR
BY COUNTRY
ON TABLE HOLD AS HLD_H01
END
-SET &H01_CNT = &LINES;
-RUN
TABLE FILE CAR
PRINT MODEL
BY COUNTRY
BY CAR
ON TABLE HOLD AS HLD_H02
END
-SET &H02_CNT = &LINES;
-RUN
-TYPE ***************************
-TYPE H01_CNT ----- &H01_CNT
-TYPE H02_CNT ----- &H02_CNT
-TYPE ***************************
-RUN
