Comments
This routine works exactly the same as VPutMap except that it uses the character data at sFont_record instead of a character equate in A. In theory, this means you can draw any character or sprite you can think up (within reason).
It will reset fracDrawLFont,(iy+fontFlags) many times, even more times if A = 8 (for whatever reason).
Example
Example code to display a capital A in the top left corner of the screen:
ld hl,0 ld (penCol),hl ld l,'A' add hl,hl ;*2 add hl,hl ;*4 add hl,hl ;*8 B_CALL Load_SFont ;load font data for 'A' to sFont_record B_CALL VPutMapRec ;display sFont_record data ...
