1. Fix bug in PRINT.SBR relating to "NO TITLE", "NO LEGEND", "NO HDR".
2. (UNIX) Support UMASK=### statement in MIAME.INI to change the file creation mask from 111 to something else. If you set UMASK=000, it will use the mask set by the shell. Otherwise it will use the specified mask. Note that the bits in the umask clear the corresponding bits in the file creation mask, which starts at 666 (rw-rw-rw-). So setting UMASK=111 will result in no change to the rw-rw-rw- mask. But UMASK=137 would result in rw-r---- (rw by the file owner, read only by members of the group, otherwise no access.)
