  The following example uses the `TEXTPTR` function to locate the **image** column `logo` associated with `New Moon Books` in the `pub_info` table of the `pubs` database. The text pointer is put into a local variable `@ptrval.`

 ### D. Returning specific text data  
  The following example locates the `text` column (`pr_info`) associated with `pub_id``0736` in the `pub_info` table of the `pubs` database. It first declares the local variable `@val`. The text pointer (a long binary string) is then put into `@val` and supplied as a parameter to the `READTEXT` statement. This returns 10 bytes starting at the fifth byte (offset of 4).
