42960: Check Token Match And Set Flag
Used by the routines at ProcessTextTokenWithAttributes, CheckObjectHasSpecialDescription and CheckObjectAttributeWithFlag.
Compares the token with the text and sets the match flag.
Input
DE Token value to check
CheckTokenMatchAndSetFlag 42960 XOR A Clear the token match flag at 42986.
42961 LD (42986),A
42964 BIT 7,D Jump ahead to PrintTokenBasedOnParameters if bit 7 of D is clear.
42966 JR Z,PrintTokenBasedOnParameters
42968 LD A,E Load 2542 and go to CheckTokenMatchAndSetFlag_Next if the low byte of the token is not 238.
42969 LD HL,2542
42972 CP L
42973 JR NZ,CheckTokenMatchAndSetFlag_Next
42975 LD A,D Read the high byte of the token.
42976 AND %00001111 Take the dictionary page (the low nibble of the token's high byte) to compare with the 9 of token 2542.
42978 CP H See whether the two values match.
42979 RET Z Return if they match.
CheckTokenMatchAndSetFlag_Next 42980 LD A,1 Write 1 to the token match flag at 42986.
42982 LD (42986),A
42985 RET Return.
