xcall GETFA(channel, keyword, field)
Arguments
channel
An expression that evaluates to a channel number, as specified in a previous OPEN statement. (n)
keyword
An expression that contains the file attribute to be returned. (See the Discussion below for a list of valid keywords.) (a)
field
The variable that will be loaded with the numeric code of the file attribute specified in keyword. (n or a)
The GETFA subroutine returns the attributes of a file. You will get unpredictable results if you specify attributes in keyword that are not characteristic of the file or device.
The following table lists the valid keywords, their corresponding file attributes, the operating systems on which they are available, and whether they require a local file system or will work on both local and remote.

a. On ISAM (Windows and UNIX), this is the size of the index file only.
b. The date and time are represented in the following format: DD-MMM-YYYY hh:mm:ss[.cc], where DD is the day, MMM is the month abbreviation (for example, JAN), YYYY is the four-digit year, hh is the hour, mm is the minute, ss is the second, and cc is the hundredth of a second, if supported.
We suggest you use the GETRFA qualifier on I/O statements like READ, FIND, and so forth, instead of using the RFA keyword.
You can use the %ISINFO routine to access additional ISAM-specific information.

See the Important note in Error trapping for information about inconsistencies that may occur after an I/O error is encountered. |
On UNIX, PRJ and GRP both return the group ID of the file’s group, and PRG and MEM both return the user ID of the file’s owner. (The only difference is that PRJ and PRG return an octal value, while GRP and MEM return a decimal value.) The UIC value is comprised of the MEM and GRP values (in other words, the group ID and the user ID concatenated).
On Windows, PRJ, GRP, PRG, MEM, and UIC all return 0.
