SET BLOB SIZE
SET BLOB SIZE
SET BLOB SIZE resizes the BLOB blob according to the value passed in size. If you want to allocate new bytes to a BLOB and want to have those bytes initialized to a specific value, pass the value (0..255) into the filler optional parameter. When you are through with a large process or interprocess BLOB, it is good idea to free the memory it occupies. To do so, write: SET BLOB SIZE(aProcessBLOB;0) The following example creates a BLOB of 16K filled of 0xFF: C_BLOB(vxData) If you cannot resize a BLOB due to insufficient memory, the error -108 is generated. You can trap this error using an ON ERR CALL interruption method. |
