AB21: print string from utility pointer
Used by the routines at AA9A, AAA0 and ABBF.
AB21 20 A6 B6 JSR $B6A6 pop string off descriptor stack, or from top of string space; returns with A = length, X = pointer low byte, Y = pointer high byte
AB24 AA TAX copy length
AB25 A0 00 LDY #$00 clear index
AB27 E8 INX increment length, for pre decrement loop
AB28 CA DEX decrement length
AB29 F0 BC BEQ $AAE7 exit if done
AB2B B1 22 LDA ($22),Y get byte from string
AB2D 20 47 AB JSR $AB47 print the character
AB30 C8 INY increment index
AB31 C9 0D CMP #$0D compare byte with [CR]
AB33 D0 F3 BNE $AB28 loop if not [CR]
AB35 20 E5 AA JSR $AAE5 toggle A, EOR #$FF. what is the point of this ??
AB38 4C 28 AB JMP $AB28 loop
