SUBROUTINE FMTASK(MASTER,ITTY,JTTY,IDISK,JDISK,KDISK)
C RENBR(/USER INTERACTION, DECSYSTEM 10 VERSION)
C
C DONALD E. BARTH, HARVARD BUSINESS SCHOOL
C
C THIS ROUTINE IS CALLED BY FORMAT STATEMENT GENERATOR
C TO ASK USER FOR NAMES OF INPUT AND OUTPUT FILES, AND
C THEN TO OPEN THESE FILES.
C
C MASTER = 0 ON INPUT, FIRST TIME THAT THE USER IS
C BEING ASKED TO SPECIFY FILES. USER IS
C REQUIRED TO SPECIFY INPUT FILE. MASTER IS
C RETURNED UNCHANGED BY THIS PROGRAM.
C = 1 ON INPUT, SECOND OR SUBSEQUENT TIME THAT
C USER IS BEING ASKED TO SPECIFY FILES. IF NO
C INPUT FILE IS SPECIFIED, THEN MASTER IS
C RETURNED UNCHANGED AND EXIT IS ASSUMED BY
C MAIN PROGRAM. IF INPUT FILE IS SPECIFIED,
C THEN MASTER IS RETURNED SET TO -1.
C ITTY = UNIT NUMBER FOR MESSAGES TO BE SEEN BY USER
C JTTY = UNIT NUMBER FROM WHICH USER RESPONSE IS READ
C IDISK = UNIT NUMBER FROM WHICH INPUT SOURCE FILE IS
C TO BE READ
C JDISK = UNIT NUMBER TO WHICH OUTPUT FORTRAN FILE IS
C TO BE WRITTEN
C KDISK = UNIT NUMBER TO WHICH OUTPUT PROOF FILE IS TO
C BE WRITTEN
