Normal syntax for LOB fields
Sirius Mods with Longstrings support allows use of most "normal" User Language syntax to access BLOB and CLOB fields. This feature is generally available as of version V7R5 of Model 204.
For example:
DEFINE FIELD LONGSTUFF WITH BLOB ... begin store record LONGSTUFF = 'How now, brown cow?' end store fr print LONGSTUFF end for end
In this request, notice how the LOB field is updated directly (in the Store Record block) and retrieved directly (in the Print statement). In general, references to LOB fields can be made in this direct fashion, without utilizing the Universal Buffer.
There are a few exceptions to this; the following constructs do not allow such direct reference to the value of a LOB field:
- The Note statement
This feature is disabled by setting the LSTRLOB system parameter to 0 (the default is 1). See the LSTRLOB description for further details.
