| 46837 | PUSH HL | Store HL (address of string to modify) | ||||||||
| 46838 | LD HL,23430 | Point HL at destination location for ASCII string | ||||||||
| 46841 | LD B,0 | Load numeric value into BC... | ||||||||
| 46843 | LD C,A | ... | ||||||||
| 46844 | CALL 47797 | Convert numeric value BC to ASCII string at address in HL (23430) | ||||||||
| 46847 | LD HL,23432 | Point HL at third digit in converted five-digit string | ||||||||
| 46850 | LD C,2 | Load C with 2 (as we can have up to two leading zeroes on a three-digit number) | ||||||||
| 46852 | LD A,(HL) | Load ASCII character at HL into A | ||||||||
| 46853 | CP 48 | If character is not a zero ("0")... | ||||||||
| 46855 | JR NZ,46863 | ...then skip ahead to 46863 | ||||||||
| 46857 | LD (HL),32 | Replace the zero character with a space (i.e. remove leading zeroes from number) | ||||||||
| 46859 | INC HL | Advance to next character in string | ||||||||
| 46860 | DEC C | Decrease C (number of remaining digits to process) | ||||||||
| 46861 | JR NZ,46852 | Loop back to 46852 if there are still digits to process | ||||||||
| 46863 | POP DE | Restore pointer to "numeric text" (originally in HL at start of this routine) into DE | ||||||||
| 46864 | LD HL,23432 | Point HL at string just created | ||||||||
| 46867 | LD BC,3 | Splice ASCII string number just generated into "numeric data" text | ||||||||
