Since I am using an OR statement in the WHERE, I'd like to post my code here.

-SET &GROUP4 = 'COAL';
-SET &XGRP4 = IF &GROUP4 EQ 'COAL' THEN 'WHERE GROUP4 EQ 'COAL UNIT' OR 'COAL NON UNIT'||';' ELSE &GROUP4;
-TYPE &|XGRP4 = &XGRP4
-EXIT

Thanks very much Confused

i call it the rule of 1-2-3
here's an example

-SET &FILTER = IF &GROUP EQ 'RETAIL' THEN 'IF CUST_ID IS ''T0020'' OR ''T9111''' ELSE
- 'IF CUST_ID IS ''T9111''' ;

1 apostrophe, then 2, then 3;
so, for you
SET &XGRP4 = IF &GROUP4 EQ 'COAL' THEN 'WHERE GROUP4 EQ ''COAL UNIT'' OR ''COAL NON UNIT'' ';

now, if you are inserting an &var, its gets a little more complicated, rule becomes 1-3-4

-SET &FILTERFAB = IF &MYFAB IS 'ALL' THEN ' ' ELSE 'IF FABCLASS IS ''' | &MYFAB | '''' ;

You could do this too...

-SET &QT='''' ;
-* (Four ticks end up to be one in the next statement *-
-*
-SET &XGRP4 = IF &GROUP4 EQ 'COAL' THEN
- ('WHERE GROUP4 EQ ' | &QT || 'COAL UNIT' || &QT | ' OR ' | &QT || 'COAL NON UNIT' || &QT ||';' )
- ELSE &GROUP4;
-*
Susannah's solution may be simpler in your case here, but the '''' technique might be something for you to consider when you have more complex statements to build.

Hi Tomsweb,

Quotes within a quote need to be double single quotes as shown:
-SET &GROUP4 = 'COAL';
-SET &XGRP4 = IF &GROUP4 EQ 'COAL' THEN 'WHERE GROUP4 EQ ''COAL UNIT'' OR ''COAL NON UNIT''||'';''' ELSE &GROUP4;
-TYPE &|XGRP4 = &XGRP4
-EXIT



Hope this helps. Smiler

Cheers,

Kerry
