BlankPage: Difference between revisions

Revision as of 00:24, 24 February 2023

The _BlankPage serves as a skeleton for new Wiki pages.

Syntax

_BlankSub arg1[, arg2]

result% = _BlankFunc(arg1[, arg2])

Parameters

arg1 is a mandatory argument
the arg2 is optional

Description

To use this skeleton click on the Edit tab above the page, then copy the raw text of this page and paste it into your new page. Change/remove sections as needed. Use this for italic and this for bold text style. To color your writings use the Text template. It takes either a color name or a #RRGGBB 32bit color, if the color part is omitted it will default to gray.

You can inline simple code one liners like w = _WIDTH

an askerisk marks a list point
- two askerisks will indent the list
  - three askerisks will indent even more

This is a definition list

The first description can follow right after a colon

or in a new line

more descriptions can follow

using list bullets with an askerisk

as already seen in the syntax above, you may use desciptions without a defininition too

you may also nest descriptions

but at some point it's cluttering the page so please use it sparingly

This is a nice piece of paper for quotes and similar things. In case of short code snippets you may use the "Cb" (code blue) template to highlight and link keywords to the Wiki pages.

FOR x = 1 TO 5
   PRINT "Hello World!"
NEXT x
END

As you see, this Text block is suitable for preformatted text, but note that the browser is still allowed to wrap too long lines. If you really need your preformatted text to be shown as is, then use a fixed text block instaed, see below.

Use this fixed text block for preformatted text, which is not even allowed to wrap long lines, such as tables etc..
As you see this very long line goes far over the display width, so please limit youself to the available space to not clutter the display too much.

Notes

This may be a sub-section for further notes like special behavior, required prerequisites etc.
If used/required, then this should always be a sub-section under the Description main section

Errors

If used/required, then this also should be a sub-section under the Description main section
This is not intended for the regular errors a SUB/FUNCTION could throw, those should be handled in the main description section.
- Rather use it for subtle things, known mis-behavior, tendency for stack overflows and seg faults etc.

Availability

v1.3
all
yes
yes
yes

The capability to load from memory was introduced in QB64-PE v3.5.0.

Examples

Example 1: Each example should have a short description.

'Place your code example here
'The "Cl" (code link) template can be used to link keywords to its
'respective Wiki page. Those words will also get highlighted.
COLOR 15,4
PRINT "Hello World!"

This template allows for a short author credit.

The output block is available for the SCREEN 0 background colors 0-7

Inside the output block use the "Ot" (output text) template for coloring

Hello World!
