Call #3D13, C= #5 ;(

Hi All! I have problems with the subject ;( When working with a disk drive (currently with a disk drive, not screw) the head begins to move to 0 track and back :(, and gives an error. Although when loading the same file from BASIC or from MMD, there is no error. Tried everything: speed (turbo/not turbo), and interrupts (di/ei), result always the same... :( Maybe necessary when calling a subroutine fill in some other registers (IX, IY,R,I :), or what else? Who knows, plz, respond... But without a direct appeal to TrDos, I can’t I want to lose compatibility with Vint... With best hopes, Vega... -+- ZxAsm v3.0
