SPLOAD directive can be used to load data from a Genstat (i.e.
GSH) spreadsheet file, specified using the
FILENAME parameter. If the file is a multi-paged spreadsheet, the
SHEETNAME parameter can be used to specify which sheet (or page) to read. If
SHEETNAME is not set, all the pages are read. By default, a summary is produced listing the data that have been read; this can be suppressed by setting option
UNNAMED options control whether to include system and unnamed structures in the summary.
SCOPE option is useful when
SPLOAD is being used within a procedure. By default, the structures are created within the procedure. Alternatively, you can set
SCOPE=external, to request that they are created in the program that called the procedure (which may itself be a procedure). Or you can set
SCOPE=global to create them in the main program itself. However, care needs to be taken to ensure that there is no conflict with any existing structures.
SPLOAD reads a structure from the spreadsheet file that has the same name as an existing structure, it will overwrite the values and attributes of the existing one, so long as the type is the same. Otherwise a VA 8 diagnostic message will be generated and
SPLOAD will fail. To force
SPLOAD to change the type of existing structures you can set the option
SPLOAD can interpret column names as suffixed identifiers (e.g
C), so long as numerical suffices are used. In this case pointers are created or modified as required (the pointer
C points to
C, etc.). If a text suffix is found (e.g.
C['first']) the data can only be loaded if the pointer has already been defined using a
ISAVE parameter can be set to a pointer to store the identifiers (i.e. column names) read from the file. The pointer can then be used to refer to the loaded data (within a procedure, for example).
