SET BLOB SIZE (blob; size{; filler})
| Parameter | Type | Description | |
| blob | BLOB |  | BLOB field or variable |
| size | Number | | New size of the BLOB |
| filler | Number | | ASCII code of filler character |
Description
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.
Examples
1. 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) SET BLOB SIZE(<>anInterprocessBLOB;0)
2. The following example creates a BLOB of 16K filled of 0xFF:
C_BLOB(vxData) SET BLOB SIZE(vxData;16*1024;0xFF)

Error Handling
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.
