## Command 'update_typ'

| This command is used to open a virtual widget with the list mask for the specified type, for which records are to be changed. See also DataView function 'iwf_lis_typ'.
| This command must not be called with a conditional instruction.
| If this command is called without transfer string - i.e. 'update_typ( )' only -, the database search is performed in the mask of the currently activated widget for the records to be changed and then these records are modified and saved. By calling the 'var' command the variables to be used (and hence the table fields to be written) are specified.
| The nested use of commands may lead to problems. This is the case when exactly the same parameter strinb is used. Example
| ### Syntax:
| update_typ({STR_EXPR| })
| ### I/O parameters:
| {STR_EXPR} | Name of entity-1 <space> Name of type
| - |
| ### Return value:
| - |
