Wildcard file names are allowed. Examples of ; valid names include 'iraf/*.fits' (Unix), d:\myfiles\f*.fits', ; (Windows) or 'Macintosh HD:Files:*c0f.fits' (Macintosh). ; ; OPTIONAL KEYWORD INPUT PARAMETER ; KEYWORDS - FITS keywords to display, as either a vector of strings or as ; a comma delimited scalar string, e.g.'testname,dewar,filter' ; If not supplied, then the default keywords are 'DATE-OBS', ; 'TELESCOP','OBJECT','EXPTIME' ; ALT1_KEYWORDS - A list (either a vector of strings or a comma delimited ; strings of alternative keywords to use if the default ; KEYWORDS cannot be found. By default, 'TDATEOBS', is the ; alternative to DATE-OBS, 'TELNAME' for 'TELESCOP','TARGNAME' ; for 'OBJECT', and 'INTEG' for EXPTIME ; ALT2_KEYWORDS - A list (either a vector of strings or a comma delimited ; strings of alternative keywords to use if neither KEYWORDS ; nor ALT1_KEYWORDS can be found. ; ALT3_KEYWORDS - A list (either a vector of strings or a comma delimited ; strings of alternative keywords to use if neither KEYWORDS ; nor ALT1_KEYWORDS nor ALT2_KEYWORDS can be found. ; /NOSIZE - if set then information about the image size is not displayed ; TEXTOUT - Controls output device as described in TEXTOPEN procedure ; textout=1 TERMINAL using /more option ; textout=2 TERMINAL without /more option ; textout=3 .prt ; textout=4 laser.tmp ; textout=5 user must open file ; textout=7 Append to existing .prt file ; textout = filename (default extension of .prt) ; EXTEN - Specifies an extension number (/EXTEN works for first extension) ; which is checked for the desired keywords. ; /NOTELESCOPE - If set, then if the default keywords are used, then the ; TELESCOPE (or TELNAME, OBSERVAT, INSTRUME) keywords are omitted ; to give more room for display other keywords. The /NOTELESCOP ; keyword has no effect if the default keywords are not used. ; OUTPUT PARAMETERS: ; None. ; ; EXAMPLES: ; (1) Print info on all'*.fits' files in the current directory using default ; keywords.

The header of each file is read, and the selected ; keywords are extracted. The formatting is adjusted so that no value ; is truncated on display. ; ; SYSTEM VARIABLES: ; TEXTOPEN (called by FITSDIR) will automatically define the following ; non-standard system variables if they are not previously defined: ; ; DEFSYSV,'!TEXTOUT',1 ; DEFSYSV,'!TEXTUNIT',0 ; ; PROCEDURES USED: ; FDECOMP, FXMOVE, MRD_HREAD, REMCHAR ; TEXTOPEN, TEXTCLOSE ; MODIFICATION HISTORY: ; Written, W.
