[Coco] assembler directive

[Dave Philipsen]

Thanks, Robert.  I had already replaced the dtb with fcb however I was 
unaware that the base year was 1900 so I corrected that.  It seems this 
call to F$STime in the sysgo program is a necessary initial call that 
gets the multitasking and clock interrupts initialized.  Without it I 
cannot get a shell.
