!   RECORD INFORMATION

!------------------------------------------------------------------------------

    DESCRIPTION       

	"This relation stores the format of tables from the PDB table library
	 (as stored in qgblibrary).  This information includes the number of 
	 parameters in the table, addressing information, etc. as described 
         in the field descriptions below.

	 During instruction expansion (in SMSG/GEN or INSTRUCT/EXPAND),
	 when an instruction of type 'TBL' (i.e. table) is encountered, the
	 Expander retrieves format information from qgformat.  This includes 
         the address of the table (within on-board computers) and whether the 
         table should be included in the SMS.

         IMTOOL IMTPZG reads in the table format defintion file, called TFPF.DAT
 	 from the ST PDB tape and creates an IMTPZA.SQL file of SQL appends and 
 	 deletes to update this relation. 

	 This is a read-only relation."
