I'quite new to this newsgroup, so maybe this problem already has been discussed. Anyway ... I'm writing a program on the 520 ST (1 MByte RAM) using TDI Modula-2/ST. The program have to multitask. I hope it'll be possible to use the standard modula statement IOTRANSFER in a scheduler. But, but, ... here is my problem: I don't know, which device to use to generate periodic interrupts (50-200 pr second would be fine). There should be a Timer-A somewhere (?). The XBIOS-functions don't seem of much help - or perhaps I just don't understand 'em well enough. Can anyone help me to some info about Timer-A, or even better: has anyone used multitasking in modula-2 on the ST.
