I have a few variables defined such as &KEY1, &KEY2, &KEY3, etc and I'm trying to access these values in a report:

-SET &KEY112847612 = 'HELLO';
TABLE FILE EMPLOYEE
PRINT DST.EMP_ID
COMPUTE MSG/A20 = '&|KEY'|EMP_ID;
END

Obviously I want Hello printed for the specific employee, but what you get is the name of the variable. Is there a way to EVAL this, so I get the right value?

You can't mix your &variables with define/compute fields like that. You have set a value for a specific variable name - &KEY112847612. That &var is not re-evaluated for every record in your table request so you cannot create another &var based on a specific record, as you're trying to do in your compute. Also EVAL is used with &vars, not real or virtual fields.

There are multiple ways to accomplish what it appears you are trying to do (COMPUTE MSG/A20=IF EMP_ID EQ '&KEY' THEN 'HELLO' ELSE '';) but I don't know if you were looking for a solution to a specific problem or needing a technique to use for some other problem.

You are trying to concatenate an Amper variable to a field in a tabel request. this will not work.

If you have a list of & variables with some text related to them, then I would suggest writing them to a file and either joining or matching or decoding the values.

Write the file in the format EMP_ID MSG.

e.g.
FILEDEF EMP_LUP DISK emp_lup.ftm

EX -LINES 2 EDAPUT FOCTEMP,EMP_LUP,CV,FILE
112847612 'HELLO'

-RUN

TABLE FILE EMPLOYEE
PRINT DST.EMP_ID
COMPUTE MSG/A20 = DECODE EMP_ID(EMP_LUP ELSE ' ');
END

Pity the lost knowledge of an old programmer!

Yeah, I'm need to be more dynamic, that is, do something based on a value in the table.

I think you're onto the right solution for my situation.

Thanks both for the quick responses.


Thanks.

-* THIS FOCEXEC WORKS FOR &KEY112847612 VALUES UP TO 19 CHARACTERS LONG
-SET &KEY112847612 = 'HELLO';
-* ADDING 1 TO THE LENGHT ADDS 1 SPACE TO &KEY112847612
-SET &KEYLEN= &KEY112847612.LENGTH + 1;
-* DETERMINE APPROPRIATE FORMAT FOR DEFINED VARIABLE MSG
-SET &KEYFORMAT = 'A' | &KEYLEN;
DEFINE FILE EMPLOYEE
MSG/&KEYFORMAT WITH EMP_ID =
SUBSTR(&KEYLEN,'&KEY112847612',1,&KEYLEN,&KEYLEN,MSG);
END
TABLE FILE EMPLOYEE
PRINT DST.EMP_ID
COMPUTE MSG/A20 = MSG|EMP_ID;
END

It sounds like he only wants the message to print for a certain pre-determined id - not for all of them. Either reading all the necessary information into amper variables or using a fex to "pre-create" the associations between ID and message, as suggested by Waz, is what you need.
