Description
When LSTRLOB=1, User Language programs can use normal field reference syntax for Lob fields. Otherwise (LSTRLOB=0), access to Lob fields must use the Buffer syntax. LSTRLOB is generally available as of Model 204 V7R5.
The default value of LSTRLOB is 1. LSTRLOB has no effect for Model 204 version V7R1.
The "normal field reference syntax" applies to all uses of a BLOB or CLOB field name except for the Note statement.
The types of allowed "normal field references" are shown in the following table, which assumes that field LOB has the BLOB or CLOB attribute:
| Type of reference | Examples |
|---|---|
| Used in expression |
%s = LOB %t = LOB:substring(%pos, %len) %xmNode:addElement('info', LOB) |
| Print statement |
print 'Value is:' and LOB |
| Field updates |
%s1 = 'x':left(3000, pad='x') add LOB = %s2 Note that the normal field reference syntax in the Store Record and Add statements does not have a provision for the Reserve clause which is available on the Buffer syntax. This is not an issue for a change LOB to %s3 Note that the only type of Change statement allowed for a field with the MINLOBE attribute is this form, using the normal field reference syntax. |
