Static Mapping
To use static application mapping an application mapping file can be read in at any point during the running of an embedded query language application with the following statement:
Windows:
set_frs frs (mapfile = full_pathname\file_name)
The parameter full_pathname\file_name is the full pathname and file name for the mapping file.
4GL uses a similar statement to read in a mapping file:
set_forms frs (
mapfile =
full_pathname\
file_name)
UNIX:
set_frs frs (mapfile = full_pathname/file_name)
The parameter full_pathname/file_name is the full pathname and file name for the mapping file.
4GL uses a similar statement to read in a mapping file:
set_forms frs (
mapfile =
full_pathname/
file_name)
VMS:
set_frs frs (mapfile = file_specification)
The file_specification parameter is the full specification for the mapping file.
4GL uses a similar statement to read in a mapping file:
set_forms frs (
mapfile =
file_specification)
When a mapping file is read in while the applications runs, it is merged with the set of previous mappings. New mappings overwrite existing mappings where they overlap. An application-level mapping file can be specified more than once during the running of an application.
