NAME: DEL_VAR PURPOSE: Program deletes an IDL variable from memory management. Unlike DELVAR, it can be called from program modules. CALLING SEQUENCE: DEL_VAR, variable INPUTS: variable: variable to be deleted OUTPUTS: None. COMMON BLOCKS: None. SIDE EFFECTS: The variable is now undefined. EXAMPLE: Define a variable... IDL> f = 1024 IDL> help, f F INT = 1024 Delete the variable... IDL> del_var, f IDL> help, f F UNDEFINED =MODIFICATION HISTORY: 15 Feb 2004 Written by Tim Robishaw, Berkeley

NAME: doc PURPOSE: Shorthand for doc_library. CALLING SEQUENCE: doc, name INPUTS: Name - A string containing the name of the IDL routine in question. KEYWORD PARAMETERS: All keywords accepted by DOC_LIBRARY are also accepted here. OUTPUTS: None. NOTES: If a routine is compiled but the directory of the routine is not in !PATH, then in order to get the documentation, you need to specify the DIRECTORY keyword must be set to the directory of the routine. MODIFICATION HISTORY: 26 Feb 2003 Written by Tim Robishaw, Berkeley 03 Oct 2005 TR. Added _REF_EXTRA options.

NAME: GETNCOL PURPOSE: Read data array of given number of columns from an ASCII data file. CALLING SEQUENCE: GETNCOL, FNAME, NUMCOL, RESULT, [,/BYTE|/INT|/LONG|/FLOAT|/DOUBLE] [,SKIP=skip][,LINES=lines][,/SILENT] INPUTS: FNAME - File name. NUMCOL - Number of columns in the file. KEYWORD PARAMETERS: /BYTE - if set, data read as byte type. /INT - if set, data read as integer type. /LONG - if set, data read as long integer type. /FLOAT - if set, data read as floating-point type. /DOUBLE - if set, data read as double-precision floating-point type. SKIP - The number of lines to skip at the start of the file. LINES - Set this keyword to a named variable that stores the number of lines read into the data array. /SILENT - Set this keyword to prevent messages. OUTPUTS: RESULT - Array containing the data read from file. COMMON BLOCKS: None. RESTRICTIONS: All data are assumed to be of the same data type. EXAMPLE: Read in 12 columns of byte type data from the file file.dat, skipping the first 3 lines and suppressing messages: IDL> GETNCOL, 'file.dat', 12, data, /BYTE, /SILENT NOTES: If no data type keyword is specifies, then floating-point is assumed.
