The G/L Buffer is a field that allows manipulation of multiple variables in a [derivation expression|DERIVATION EXPRESSIONS] in [UPGLF].  The variables, and their meaning are as described for the IDIF [X_INF_VARIABLE_NAME (01)].

This variable, if left alone will return a 672 byte value which is a concatenation of the values used in the generation of each record for the GL file.  Using the SQL substring function [SUBSTR], we can extract bits and pieces and manipulate it within the derivation expression.

This can be used in quite sophisticated derivations, as shown in these examples:
# [Burden Code manipulation|GL BUFFER EXAMPLE 01]
# [Using GL Buffer to determine bypassing|GL BUFFER EXAMPLE 02]
# [Changing Dates based on Journal Source|GL BUFFER EXAMPLE 03]

The substring values for GL BUFFER are as follows:
