.PrintLegalStatus

 LDA #125               ; Print recursive token 125 ("LEGAL STATUS:) followed
 JSR spc                ; by a space

 LDA #19                ; Set A to token 133 ("CLEAN")

 LDY FIST               ; Fetch our legal status, and if it is 0, we are clean,
 BEQ st5                ; so jump to st5 to print "Clean"

 CPY #40                ; Set the C flag if Y >= 40, so C is set if we have
                        ; a legal status of 40+ (i.e. we are a fugitive)

 ADC #1                 ; Add 1 + C to A, so if C is not set (i.e. we have a
                        ; legal status between 1 and 49) then A is set to token
                        ; 134 ("OFFENDER"), and if C is set (i.e. we have a
                        ; legal status of 50+) then A is set to token 135
                        ; ("FUGITIVE")

.st5

 JMP plf                ; Print the text token in A (which contains our legal
                        ; status) followed by a newline, returning from the
