PA_SetBooleanVariable (aVariable; newValue)
| Parameter | Type | Description | |
| aVariable | PA_Variable * |  | Pointer to the variable to access |
| newValue | char | | New value for aVariable |
Description
The routine PA_SetBooleanVariable sets the content of the boolean variable pointed to by aVariable to newValue.
WARNING
The kind of variable pointed to by aVariable is set to eVK_Boolean by the routine, even if it was not its previous kind.
Make sure that you do not change 4D variable kinds (using PA_GetVariable), especially in compiled mode.
Remember that True = 1 and False = 0 for 4D.
Example
Use macros for True and False.
#define FALSE4D ((char)0)
#define TRUE4D ((char)1)
void mySetBooleanVariable(PA_Variable *v, char b)
{
if(PA_GetVariableKind(*v) == eVK_Boolean)
{
if(b)
PA_SetBooleanVariable(v,TRUE4D);
else
PA_SetBooleanVariable(v,FALSE4D);
}
}

Error Handling
PA_GetLastError keeps the last error that occurred before calling the routine.
