# CALL ADJUST ## Effect Enables the internal lightpen interface. It is required to use `CALL ADJUST` before using `PAD()` with the values 20 to 23. This instruction enables the lightpen interface (bit6 of the VDP R#8) but not the lightpen interrupts (bit5 of the VDP R#0), and sets the system variables XOFFS=23 and YOFFS=0. Since it doesn't enable the light pen interrupts, this command is not enough to make `GTPAD`/`PAD()` functional. The lightpen interrupts will have to be enabled via VDP register write. This instruction is available **only** with the MSX2 computers manufactured by _Daewoo_: - AVT CPC-300 - Bawareth Perfect MSX2 - Daewoo CPC-300 - Daewoo CPC-400 - Daewoo CPC-400S - Talent DPC-300 - Wandy CPC-300 It is also maybe available with the _Sanyo MPC-X Graphic Expander Unit_ and the _Sanyo MPC-27_ computer. ## Syntax `CALL ADJUST` # Related to `PAD()` ## Compatibility Only MSX2 computers manufactured by _Daewoo_. This instruction is part of Hangul BASIC on the Korean MSX2 computers. ## Source Retrieved from "https://www.msx.org/wiki/CALL_ADJUST"
