The FSLIST Procedure

PROC FSLIST Statement

The PROC FSLIST statement initiates the FSLIST procedure and specifies the external file to browse. Statement options allow you to modify the default behavior of the procedure.

PROC FSLIST Statement Requirements
The PROC FSLIST statement must include one of the following arguments that specifies the external file to browse.

FILEREF=file-specification
DDNAME=file-specification
DD=file-specification

specifies the external file to browse. file-specification can be one of the following:

'external-file': is the complete operating environment file specification (called the fully qualified pathname under some operating enfironments) for the external file. You must enclose the name in quotation marks.
fileref: is a fileref that has been previously assigned to the external file. You can use the FILENAME statement to associate a fileref with an actual filename. For information about the FILENAME statement, see the section on statements in SAS Language Reference: Dictionary.

UNIT=nn

defines the FORTRAN-style logical unit number of the external file to browse. This option is useful when the file to browse has a fileref of the form FTnnF001, where nn is the logical unit number specified in the UNITS= argument. For example, you can specify

proc fslist unit=20;

instead of

proc fslist fileref=ft20f001;

This form of fileref was used for a variety of SAS System output files in Version 5 SAS software under the MVS, CMS, and VSE operating environments. For example, the SAS log was written to a file with the fileref (DDname) FT11F001.

PROC FSLIST Statement Options
The following options can be used with the PROC FSLIST statement:

CAPS NOCAPS

controls how search strings for the FIND command are treated:

CAPS

translates search strings into uppercase unless they are enclosed in quotes. For example, with this option in effect, the command

find nc

locates occurrences of NC, but not nc. To locate lowercase characters, enclose the search string in quotes:

find 'nc'

NOCAPS does not perform a translation; the FIND command locates only those text strings that exactly match the search string.

The default is NOCAPS. You can use the CAPS command in the FSLIST window to change the behavior of the procedure while you are browsing a file.

CC FORTCC NOCC

indicates whether carriage-control characters are used to format the display. You can specify one of the following values for this option:

uses the native carriage-control characters of the host operating environment.

FORTCC

uses FORTRAN-style carriage control. The first column of each line in the external file is not displayed; the character in this column is interpreted as a carriage-control code. The FSLIST procedure recognizes the following carriage-control characters:

+	skip zero lines and print (overprint)
blank	skip one line and print (single space)
0	skip two lines and print (double space)
-	skip three lines and print (triple space)
1	go to new page print.

NOCC

treats carriage-control characters as regular text.

If the FSLIST procedure can determine from the file's attributes that the file contains-carriage control information, then that carriage-control information is used to format the displayed text (the CC option is the default). Otherwise, the entire contents of the file are treated as text (the NOCC option the default).

Note: Under some operating environments, FORTRAN-style carriage control is the native carriage control. For these environments, the FORTCC and CC options produce the same behavior. [cautionend]

HSCROLL=n|HALF|PAGE

indicates the default horizontal scroll amount for the LEFT and RIGHT commands. The following values are valid:

n	sets the default scroll amount to n columns.
HALF	sets the default scroll amount to half the window width.
PAGE	sets the default scroll amount to the full window width.

The default is HSCROLL=HALF. You can use the HSCROLL command in the FSLIST window to change the default scroll amount.

NOBORDER

suppresses the sides and bottom of the FSLIST window's border. When this option is used, text can appear in the columns and row that are normally occupied by the border.

NUM NONUM

controls the display of line sequence numbers in files that have a record length of 80 and contain sequence numbers in columns 73 through 80. NUM displays the line sequence numbers; NONUM suppresses them. The default is NONUM.

OVP NOOVP

indicates whether the carriage-control code for overprinting is honored:

OVP	causes the procedure to honor the overprint code and print the current line over the previous line when the code is encountered.
NOOVP	causes the procedure to ignore the overprint code and print each line from the file on a separate line of the display.

The default is NOOVP. The OVP option is ignored if the NOCC option is in effect.
