FIX: "Syntax Error" with EVAL of ALL or LTRIM in SELECT-SQL

MORE INFORMATION

Steps to Reproduce Behavior

1. Run the following code from a program (.PRG) file:

         CLOSE DATABASES ALL
         SET SAFETY OFF
   
         * Create table and index.
         CREATE table temp_table (cBTN c(2), cUsageTl c(10))
         INDEX on cUsageTl tag cUsageTl
   
         SET SAFETY ON
   
         * Insert some records.
         FOR lnj = 1 to 10
            INSERT into temp_table (cBTN, cUsageTl) values ("91", "Sp800/W")
            INSERT into temp_table (cBTN, cUsageTl) values ("91", "Sp800/X")
            INSERT into temp_table (cBTN, cUsageTl) values ("91", "Sp800/Y")
         ENDFOR
   
         * Initialize variables to Evaluate.
         lcService91="Sp800/W"
         lcService92="Sp800/X"
         lcService93="Sp800/Y"
   
         * Issue SELECT with trailing, no and leading space.
         SELECT *, .t. FROM temp_table WHERE temp_table.cUsageTl = ;
            EVALUATE("lcService"+ALLTRIM("91 ")) ;
            INTO CURSOR Temp2
   
         SELECT *, .t. FROM temp_table WHERE temp_table.cUsageTl = ;
            EVALUATE("lcService"+ALLTRIM("92")) ;
            INTO CURSOR Temp3
   
         * It fails with the leading space.
         SELECT *, .t. FROM temp_table WHERE temp_table.cUsageTl = ;
            EVALUATE("lcService"+ALLTRIM(" 93")) ;
            INTO CURSOR Temp4
   							

Demonstration of Workaround

   SELECT *, .t. FROM temp_table ;
      WHERE temp_table.cUsageTL = EVALUATE(STRTRAN("lcService" ;
      + (" 91")," ","")) ;
      INTO CURSOR Temp4
