581.0. ""IF &LINES EQ 0" question" by PACUK::GARMCS::MCSHANEG (Deceptively Co-Operative) Thu May 12 1994 13:22

     Hi,

	I have a .fex which uses a loop to produce reports based on an 	
	initial collection of codes. This loop works fine but there are
        certain reports that do not fit the criteria and therefore a test
        of &LINES equals 0 and I do not want to produce an output file.

	A simple IF &LINES EQ 0 THEN GOTO blah apparently only allows 
        you to exit from the procedure/loop, is there some way I can 
        continue processing but not create a blank (heading only) report 
        file and not encounter a -RUN as this closes open files (eg the 
        file used to -READ from for the loop) ?


	-LOOP
	 TABLE FILE BLAH
	 SUM X AND Y AND X
	 BY X NOPRINT
	 END
        -RUN
	-IF &LINES EQ 0 GOTO ALLDONE;
	-GOTO LOOP 
	-ALLONE
	-QUIT

	
         Ta,
         Gary.
