PRINT # USING Formatted Output to File
PRINT #filenum, USING strexpr; exprlist[;]
Writes to a specified disk file an image of what would be displayed on
screen by a corresponding PRINT USING statement.
filenum The number under which the file was OPENed.
strexpr A string variable or constant specifying the format in
which the data is to be printed (see below).
exprlist Numeric and/or string expressions to print. Each
expression must be separated from the one after it by
either a comma or a semicolon.
; If included at the end of the statement, suppresses the
usual carriage return and line feed.
Formatting options:
The following symbols may be used in strexpr:
Symbol Meaning
! Print only the first character of a string expression.
\ \ Print only the first n characters of a string expression,
where n is the number of spaces between the two
backslashes. If n is larger than the number of characters
in the string expression, QuickBASIC pads the string
expression on the right with space characters.
& Print a string expression without reformatting it.
. Specifies the position of the decimal point in a numeric
expression.
# A place-holder. If the numeric expression has more digits
to the right of the decimal point than the format string
has #s, QuickBASIC rounds. If the numeric expression has
more digits to the left of the decimal point than the
format string has #s, QuickBASIC prints all the digits to
the left of the decimal point and also prints a percent
sign (%) to the left of the number. If the numeric
expression has fewer digits to the left of the decimal
point than the format string has #s, QuickBASIC right-
justifies the number; that is, it pads the number on the
left with spaces. (But if there are any #s to the left of
the decimal point in the format string, QuickBASIC always
prints at least one digit--a 0 if necessary--to the left
of the decimal point.)
+ Print a plus or minus sign, as appropriate, to the left of
the number. The sign is always printed immediately to the
left of the number.
- Print a minus sign immediately to the right of a negative
number (the minus sign should appear after the place
holders in the format string).
$$ Print a dollar sign immediately to the left of the number.
The double dollar sign also acts as a place holder for two
additional digits to the left of the decimal point, one of
which is the dollar sign itself. The dollar sign cannot be
prefixed to a number printed in exponential format.
** Fill any leading spaces with asterisks. The double
asterisk also acts as a place holder for two additional
digits to the left of the decimal point.
**$ Print a dollar sign immediately to the left of the number,
and fill any remaining leading spaces with asterisks. The
combination of two asterisks and a dollar sign also acts
as a place holder for three additional digits, one of
which is the dollar sign.
^^^^ Print a number in exponential format. The four carets
should appear after all place holders in the format
string.
_ Print next character as a literal. The combination _#, for
example, allows you to include a number sign as a literal
in your numeric format.
[other] Characters other than the foregoing may be included as
literals in the format string. Thus, for example, a single
dollar sign may be positioned to the left of a series of
place holders (#s) to achieve vertically aligned dollar
signs, and space characters may be placed at the right
side of the format string to achieve horizontal separation
between a series of numbers.
----------------------------------------------------------------------
Notes: PRINT # USING outputs exactly the same characters that
would appear on screen in response to a PRINT USING
statement. Commas between expressions, for example, result
in the insertion of space.
If an expression to be output contains significant quote
marks or commas, you should surround it with quote marks
by means of CHR$(34); otherwise, when you input these
fields, QuickBASIC will interpret the significant commas
or quotes as delimiters.
Double-precision numbers in IEEE format may have three-
digit exponents. To print numbers with three-digit
exponents, use five carets instead of four.
