6.5 Initialization

Name: »Line-A initialization«
Line-A number: $A000
Syntax: See 'Bindings for linea_init'
Description: This Line-A function serves to inquire the address of the Line-A parameter block.
Return value: The function returns in d0 and a0 a pointer to the parameter block. In a1 a pointer to a field with 3 addresses of the system fonts will be returned, and in a2 a pointer to the start addresses of the Line-A routines.

Note: Some bindings, as that from TC, for instance, do not return the addresses to the caller, but set the parameters for the call of the Line-A functions themselves internally.
Availability: All TOS versions.
