The **PRINT #, USING** statement is used to [PRINT](PRINT) formatted text data to a file.
|
||
|
||
## Syntax
|
||
|
||
> **PRINT *filenumber%,*** [*text$*{;|,}] **USING *template$*; *variable***[; ...][{;|,}]
|
||
|
||
## Parameter(s)
|
||
|
||
* [INTEGER](INTEGER) *filenumber* refers to the file number [OPEN](OPEN)ed previously followed by a [comma](comma).
|
||
* Literal or variable [STRING](STRING) *text$* can be placed between PRINT and USING or it can be included in the *template*.
|
||
* A [semicolon](semicolon) or [comma](comma) may follow the *text* to stop or tab the print cursor before the *template* [PRINT](PRINT).
|
||
* The literal or variable [STRING](STRING) *template* should use the template symbols to display each variable [Variable Types](Variable-Types) in the list following it.
|
||
* The list of data *variables* used in the *template* are **separated by semicolons** after the template string value.
|
||
* In **QB64** ONE [semicolon](semicolon) or [comma](comma) may follow the variable list to stop the print cursor for pending prints. QB only allowed a semicolon.
|
||
|
||
## Usage
|
||
|
||
* **If the *template* string is omitted or symbols don't match the *variable(s)* an "Illegal Function Call" [ERROR Codes](ERROR-Codes) will occur!**
|
||
* The list of data variables used in the template are **separated by semicolons** after the template string value.
|
||
* The variables should be listed in the order that they are used in the template from left to right.
|
||
* Normal text is allowed in the template also (see example).
|
||
* **NOTE:** If the numerical value exceeds the template's integer digit range a % symbol will appear in the leftmost digit area.
|
||
* **WARNING: The numbers displayed are rounded so the actual values are never changed and are actually more accurate.**
|
||
|
||
Template is a literal or variable [string](STRING) using the following formatting characters:
|
||
|
||
| & | Prints an entire string value. STRING length should be limited as template width will vary. |
|
||
| -- | -- |
|
||
| \ \ | Denotes the start and end point of a fixed string area with spaces between(LEN = spaces + 2). |
|
||
| ! | Prints only the leading character of a string value. Exclamation points require underscore prefix. |
|
||
| # | Denotes a numerical digit. An appropriate number of digits should be used for values received. |
|
||
| ^^^^ | After # digits prints numerical value in exponential E+xx format. Use ^^^^^ for E+xxx values.* |
|
||
| . | Period sets a number's decimal point position. Digits following determine rounded value accuracy. |
|
||
| ,. | Comma to left of decimal point, prints a comma every 3 used # digit places left of the decimal point. |
|
||
| + | Plus sign denotes the position of the number's sign. + or - will be displayed. |
|
||
| - | Minus sign (dash) placed after the number, displays only a negative value's sign. |
|
||
| $ | Prints a dollar sign immediately before the highest non-zero # digit position of the numerical value. |
|
||
| ** | Prints an asterisk in any leading empty spaces of a numerical value. Adds 2 extra digit positions. |
|
||
| **$ | Combines ** and $. Negative values will display minus sign to left of $. |
|
||
| _ | Underscore preceding a format symbol prints those symbols as literal string characters. |
|
||
|
||
**Note: Any string character not listed above will be printed as a literal text character.**
|
||
|
||
* Any # decimal point position may be specified. The exponent is adjusted with significant digits left-justified.
