A couple ideas for new HOLD formats came up during one of the many 'hallway' meetings that always occur at Summit this year. The AMPER idea is for something like this:

TABLE FILE DATA
PRINT or SUM SOMETHING
WHERE ONLY_ONE_RECORD_RETURNED
ON TABLE HOLD INTO &ERVAR
END

We normally use -READ to get database values into amper variables all the time but it takes extra coding, i.e.:

TABLE FILE DATA
PRINT or SUM SOMETHING
WHERE ONLY_ONE_RECORD_RETURNED
ON TABLE HOLD FORMAT ALPHA
END
-RUN
-READ HOLD &ERVAR.An.

In most cases this is the preferred method since it's the most flexible in terms of multiple variables and multiple records that can be processed by Dialog Manager looping. But in the case where only one value is needed, the HOLD INTO &ERVAR would be much quicker and provide an easier to understand source code.

Another good idea, these "hallway" meetings sound interesting.


An interesting extension to this would be :

TABLE FILE DATA
PRINT or SUM FieldA B
ON TABLE HOLD INTO &Var_
END

and the result would be:

&Var_FieldA001
&Var_FieldA002
&Var_FieldA00n
&Var_FieldB001
&Var_FieldB002
&Var_FieldB00n

Although this could be quite dangerous, I think it could also be quite useful.

The only other way to do this is with -READ loop or the following:

TABLE FILE CAR
PRINT 
COMPUTE CNTR/I3 = LAST CNTR + 1 ; NOPRINT
COMPUTE SETVAR/A36 = '-SET &|CTY' || FTOA(CNTR,'(F3L)','A3') || '=''' || COUNTRY || ''';' ;
BY COUNTRY NOPRINT
ON TABLE SET HOLDLIST PRINTONLY
ON TABLE SAVE AS FEX_CODE
END
-RUN
-INCLUDE FEX_CODE
-? &CTY

-READFILE looks very useful in the same way 'FIXFORM FROM HOLDFILE' saves typing, and insulates changes in the hold file from failing the procedure. I can't remember how many times I added a field in a hold file because of a change in one part of the FEX and didn't update a FIXFORM or -READ that depended on an exact sequence of named columns (until I noticed my updated data had shifted into the wrong columns, i.e., NAME '1991Steve ', ADDRESS 'Smith421 Bel', CITY 'twayWashington', etc.).

But, HOLD INTO for one value should still process faster and provide cleaner code that's easier to understand. I think it would be an excellent addition.

Looks like -READFILE is exactly what you wanted to ask for. Just one extra line.
