Basic DM question

Hi,

Here's a vry basic DM problem I can't seem to get around.

This is a simplified piece of code that fails with the following error:

(FOC295) A VALUE IS MISSING FOR: TEST3



-DEFAULT &LEVEL = 3;

-SET &MAX_LEVEL = 2;

-SET &TEST1 = 'APPLE';
-SET &TEST2 = 'ORANGE';

-SET &FRUIT = IF &LEVEL GT &MAX_LEVEL THEN '' ELSE &TEST.&LEVEL;

-TYPE &FRUIT

Don't tell me I have to use clumsy GOTO's and labels to avoid this problem.

Any ideas?

Thanks,

Pietro.

Give me a piece of advice? How do you write a moderately complex piece of focus code without GOTOs and Labels.

Do you have anything against -REPEAT?

-DEFAULT &LEVEL = 3;
-SET &MAX_LEVEL = 2;

-REPEAT STARTIT &MAX_LEVEL TIMES
-DEFAULT &TEST.&LEVEL = ' '
-STARTIT

-SET &TEST1 = 'APPLE';
-SET &TEST2 = 'ORANGE';
-SET &FRUIT = IF &LEVEL GT &MAX_LEVEL THEN '' ELSE &TEST.&LEVEL;
-TYPE &FRUIT

Easier. Set a default value to &TEST.&LEVEL independently of &LEVEL value.


-DEFAULT &LEVEL = 3;
-SET &MAX_LEVEL = 2;

-SET &TEST1 = 'APPLE';
-SET &TEST2 = 'ORANGE';

-DEFAULT &TEST.&LEVEL = ' ' ;

-SET &FRUIT = IF &LEVEL GT &MAX_LEVEL THEN ' ' ELSE &TEST.&LEVEL;
-TYPE Fruit - &FRUIT[/code]Regards,
Mikel

Nothing against -REPEAT, in fact I love it.

Nothing against -DEFAULT either.

Just assumed DM would stop parsing the line after the first condition becoming true, silly me.

Thinking a little more, why do we need -IF?


-DEFAULT &LEVEL = 2 ;
-SET &MAX_LEVEL = 2;

-SET &TEST1 = 'APPLE';
-SET &TEST2 = 'ORANGE';
-DEFAULT &TEST.&LEVEL = ' ' ;

-SET &FRUIT = &TEST.&LEVEL ;
-TYPE Fruit - &FRUIT
And finally, I think that a simple DECODE is the best solution...

-DEFAULT &LEVEL = 3 ;
-SET &FRUIT = DECODE &LEVEL (1 'APPLE' 2 'ORANGE' ELSE ' ') ;
-TYPE Fruit - &FRUIT
Regards,
Mikel
