LPRINT USING - QB64Official/qb64 GitHub Wiki
The LPRINT USING statement sends formatted data to LPT1, the parallel port printer.
Syntax
LPRINT [text${;|,}] USING template$; variable[; ...][{;|,}]
Parameter(s)
- Literal or variable STRING text$ can be placed between LPRINT and USING or it can be included in the template$.
- A semicolon or comma may follow the text$ to stop or tab the print cursor before the template$ LPRINT.
- The literal or variable STRING template$ should use the template symbols to display each variable 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.
- A semicolon or comma may follow the variable list to stop or tab the print cursor for pending prints.
Description
- The variable list should be listed in the order that they are used in the template from left to right.
- If the template string is omitted or symbols don't match the variable(s) an "Illegal Function Call" ERROR Codes will occur.
- No more than 25 # digit places are allowed in a template number or an ERROR Codes will occur.
- Can convert numerical exponential or scientific notation values to normal decimal point values using less digits.
- NOTE: If the numerical value exceeds the template's digit range a % symbol will appear in the leftmost digit area.
Template is a literal or variable 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.
