Returns or sets the size of a BLOB field. Before assigning data to the BLOB using the string slicing technique, if the BLOB does not yet contain any data you must set its size using PROP:Size. Before assigning additional data that will increase the amount of data in the BLOB (using the string slicing technique), you must reset its size using PROP:Size.

**Example:**

**Names   FILE,DRIVER('TopSpeed')**

**NbrKey   KEY(Names:Number)**

**Notes    BLOB        !Can be larger than 64K**

**Rec      RECORD**

**Name      STRING(20)**

**Number    SHORT**

**         END**

**        END**

**BlobSize    LONG**

**BlobBuffer1 STRING(65520),STATIC  !Maximum size string**

**BlobBuffer2 STRING(65520),STATIC  !Maximum size string**

**WinView  WINDOW('View BLOB Contents'),AT(0,0,320,200),SYSTEM**

**          TEXT,AT(0,0,320,180),USE(BlobBuffer1),VSCROLL**

**          TEXT,AT(0,190,320,180),USE(BlobBuffer2),VSCROLL,HIDE**

**         END**

** CODE**

** OPEN(Names)**

** SET(Names)**

** NEXT(Names)**

** OPEN(WinView)**

** BlobSize = Names.Notes{PROP:Size}    !Get size of BLOB contents**

** IF BlobSize > 65520**

**  BlobBuffer1 = Names.Notes[0 : 65519]**

**  BlobBuffer2 = Names.Notes[65520 : BlobSize - 1]**

**  WinView{PROP:Height} = 400**

**  UNHIDE(?BlobBuffer2)**

** ELSE**

**  BlobBuffer1 = Names.Notes[0 : BlobSize - 1]**

** END**

** ACCEPT**

** END**
