Loads Genstat spreadsheet files.
PRINT = string token
|What to print (
SCOPE = string token
SPLOAD is used within a procedure, this allows the data structures to be created in program that called the procedure (
SCOPE=external) or in the main program itself (
SCOPE=global) rather than within the procedure (
REDEFINE = string token
|Whether to allow existing structures to have their type redefined (
SYSTEM = string token
|Whether to include Genstat system structures in the catalogue (
UNNAMED = string token
|Whether to include unnamed structures in the catalogue (
TEMPMISSING = string token
|Whether to read temporarily missing values as missing (
FILENAME = texts
|Names of spreadsheet files
SHEETNAME = texts, variates or scalars
|Names or numbers of the sheets to read from each file; default
* reads them all
ISAVE = pointers
|Stores the identifiers of the structures loaded from each file
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.
catalogue lists the contents of the file (default);
directory includes the directory details with the name of the file in the catalogue, and
summary prints a summary of the values in each data structure in the file.
By default, unnamed structures are excluded from the catalogue, but you can set the
UNNAMED option to
yes to include them.
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
TEMPMISSING option controls the input of temporarily missing values. These are values that have been set to missing temporarily in the spreadsheet, and for which the original (non-missing) values are still available. The default is to read the original values, but you can set
TEMPMISSING=yes to read them as missing values instead.
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).
