Converting DO and RF Information
The FAL provides two functions for converting specific attribute information
from a dataset into character strings: datasetGetDsorgString, and
datasetGetRecfmString.
Converting the Dataset Organization (DO) Type Value
datasetError = datasetGetDsorgString (dsorg, text)
The datasetGetDsorgString function converts the dataset organization (DO)
type to a three-byte character string. The DO type is specified by dsorg[2] in
DATASET_FIND_DATA. Table 6-10 lists the datasetGetDsorgString
arguments and return values.

char [3]
Value of dsorg[2] (two bytes) obtained by the attribute acquisition function
datasetGetFileInformation, datasetFindFirstFile, or
datasetFindNextFile.
Character string indicating the dataset organization (DO) type (3 bytes):
PS physical sequential organization
VS VSAM organization
DA direct access organization
PO Partial organization
** Other than above types
Return value 0
-1
Normal end
Error end
Converting the Record Format (RF) Type Value
datasetError = datasetGetRecfmString (recfm, text)
The datasetGetRecfmString function converts the record format (RF) type to
a five-byte character string. The RF type is specified by recfm in
DATASET_FIND_DATA. Table 6-11 lists the datasetGetRecfmString
arguments and return values.
