The $ZFILEATTRIBUTES function returns an item of information about a specified file. The $ZFILEATTRIBUTES function is analogous to the DCL Lexical function F$FILE_ATTRIBUTES.
The format for the $ZFILEATTRIBUTES function is:
$ZFILE[ATTRIBUTES](expr1,expr2)
The first expression specifies the target file
The second expression specifies the item keyword identifying the information for $ZFILEATTRIBUTES() to return; keywords may be upper-, lower-, or mixed-case
$ZFILEATTRIBUTES() provides a tool for examining the RMS characteristics of a file from GT.M.
