This function retrieves information about attributes defined in a grid. The attribute list is returned as a string with each attribute name separated by commas.
Note: See STRSPLIT to separate the attribute list.
In this example, we retrieve information about the attributes defined in a grid structure:
nattr = EOS_GD_INQATTRS(gridID, attrlist)
Result = EOS_GD_INQATTRS( gridID, attrlist [, LENGTH=variable] )
Number of attributes found or (–1) if failure.
Grid id (long) returned by EOS_GD_CREATE or EOS_GD_ATTACH.
A named variable that will contain the attribute list (string) with entries separated by commas.
Set this keyword to a named variable that will contain the length of the attribute list as a long integer.
