- .ch Invoking BROWSE
- .; invoking more
- To run BROWSE, type the DCL command "BROWSE", followed by the name of
- the file which you wish to browse.
- No default filetype is used.
- For example, the command
- .b;########BROWSE XYZ
- .b;is equivalent to
- .b;########BROWSE XYZ.
- .b;BROWSE recognizes several options, which you may supply in any
- order:
- .lm+8
- .b.i-4;/BG
- .x /BG qualifier
- .br;The BitGraph terminal is VT100-compatible,
- but in its native mode it displays 65 lines on the screen.
- The VMS terminal driver coerces the BitGraph to VT100 mode
- when BROWSE is invoked.
- To run the BitGraph in native mode, use the /BG option.
- This restores the terminal to native mode after the terminal
- driver has set it to VT100 mode.
- .b
- This option may not be used if BROWSE is called from FLIST,
- since the screen buffer has already been allocated.
- .;
- .b.i-4;/MARKS
- .x /MARKS qualifier
- .br;The /MARKS option directs BROWSE to show the file address
- and number of each record in the input file.
- The resulting prefix-display (file address and record number)
- may be toggled on and off with the M-command.
- .b
- .x /JOIN qualifier
- .x /SQUEEZE qualifier
- The /JOIN and /SQUEEZE options may alter the displayed record
- number from the true value seen by VMS.
- The file address, however, is unaffected.
- .;
- .b.i-4;/NOJOIN
- .x /JOIN qualifier
- .br;BROWSE examines the record attributes of your file.
- If it does not have the carriage-control attribute,
- then BROWSE assumes this is a file with embedded carriage-control
- characters such as that produced by RUNOFF.
- For this case, the JOIN option is, by default, active.
- When JOIN is active, BROWSE joins together records which do not
- end with a LINE-FEED, so that overstrikes constructed using RETURN
- may be shown on a single display line.
- .b
- To disable this mode (and see the true record structure of a binary
- file, for instance), use the /NOJOIN command.
- .;
- .b.i-4;/OVER
- .x /OVER qualifier
- .br;If no value is specified, /OVER initially places BROWSE in a
- display mode where backspace, RETURN and TAB are shown respectively
- as "_^H", "_^M" and "_^I", rather than used as carriage control.
- This may be toggled with the O-command.
- .b
- If the value 2 is given (e.g., "/OVER:2"), then BROWSE treats
- the O-command as a three-state toggle.
- The third state causes all control characters to be shown as ".".
- .;
- .b.i-4;/SQUEEZE
- .x /SQUEEZE qualifier
- .br;Normally BROWSE displays your file exactly as it really is.
- However, formatted files (such as those produced by RUNOFF)
- may contain a lot of blank lines.
- The /SQUEEZE option directs BROWSE to combine into a single "record"
- sequences of records which contain only whitespace characters
- (e.g., space, TAB, RETURN).
- .b
- It does not affect the (very rare) cases in which a single
- record contains a sequence of LINE-FEED characters embedded
- within non-whitespace characters.
- .;
- .b.i-4;/TRIM
- .x /TRIM qualifier
- .br;Depending on the current state of ruler-mode,
- the J-command causes BROWSE to move the cursor to the next end-of-line,
- or to simply scroll to put the rightmost end-of-line on the
- screen.
- BROWSE normally counts trailing blanks.
- They are, after all, part of the file.
- To cause BROWSE to ignore trailing blanks,
- use the /TRIM option.
- .;
- .b.i-4;/WIDE
- .x /WIDE qualifier
- .br;The /WIDE option tells BROWSE to assume that your terminal
- is really set to 132-column mode, even though you have told VMS
- (via a "SET#TERMINAL") that it is not.
- .b
- This option may not be used if BROWSE is called from FLIST,
- since the screen buffer has already been allocated.
