Summary |
A keyword used with function variables: ^[funcname parameter(s)]. This syntax can be used anywhere that a regular 3B2 variable can be used: in show strings, in scripts, in expressions, etc. Function variables are a V8 feature that uniforms variable use and functions into a readable syntax. The 'show' function is defined for completeness within showstrings and behaves like <?show>, but does also enable use of show strings and showstring functions within scripts. |
Example extract |
The following show string will display the current value of the th command (text height).
