GIPSY applications programmers should be aware of the fact that the so called undefined value (or BLANK as it is called in FITS terminology) is a fixed value which can only be different across different computer operating systems. ... The subroutine SETFBLANK can be used to set one value to BLANK; subroutine SETFNBLANK sets a whole array to BLANK. For the sake of speed it is advisable to compare data values directly with the system defined BLANK instead of using the slower function FBLANK. ...
