PA_Dial4DGetReal (dialog; variable) → double
| Parameter | Type | Description | |
| dialog | PA_Dial4D | → | Dialog reference |
| variable | char* | → | Name of the variable to access |
| Function result | double | ← | Value of variable |
Description
The routine
PA_Dial4DGetReal
gets the value of a variable whose name is
variable
and returns its value as a double. This command is preferred to the
PA_Dial4DGetVariable
call because it handles the type casting for the developer.
By default,
variable
needs to be a null terminated C string. If you have previously called
PA_UsePStrings,
you must pass a Pascal string to the command.
By default,
varName
needs to use Macintosh characters set on Macintosh, and ANSI characters set under Windows. You can call
PA_UseMacCharacters
or
PA_UseAnsiCharacters
to use specifically Macintosh or ANSI characters.
