A blob (Binary Large Object Block) is a collection of bytes containing arbitrary values that may include null characters. It is terminated by a length value. To define a Blob Object, use the format:
blob obj_name;
Generally, a Blob object maximum size is the same as the maximum size of an integer. This size is dependent on the computer architecture, whether 16 bit, 32 bit, or 64 bit. For most computer systems, the maximum size is 4 GB.
There are two ways to build a blob object:
Highlight “Blob” in the Classes list of the Browse dialog box and click Add.
When the Define Window opens, select Class, then select Blob from the associated drop-down list
See the e-Biz Impact ODL Guide for
details on blob methods.
