	Command 4d_language_referen<<sql_name>> \|<<$sql_name>> \| <<[sql_name]sql_name>> \| :sql_name\|:$sql_name\|:sql_name.sql_name

Description

A 4d_language_reference argument specifies the 4D variable or field name (sql_name) to which data will be assigned. This name can be passed in one of the following manners:

<<sql_name>>
<<$sql_name>> (*)
<<[sql_name]sql_name>> (corresponds to the standard 4D syntax: [TableName]FieldName)
:sql_name
:$sql_name (*)
:sql_name.sql_name (corresponds to the standard SQL syntax: TableName.FieldName)

(*) In compiled mode, you cannot use references to local variables (beginning with the $ symbol).
