Substring notationC2X Format: Function-invocationOperands: CharacterOutput: C2X(’charstring’) converts the character-string argument tohexadecimal characters representing the same bit pattern. Null argumentsreturn a null string.If the result is not too long, the length of the result is two times the lengthof the ’charstring’ argument.ExamplesC2X(’’) has value ’’C2X(’n’) has value ’00’C2X(’1’) has value ’F1’C2X(’a’) has value ’81’C2X(’1234567R’) has value ’F1F2F3F4F5F6F7D9’D2B Format: Function-invocationOperands: Character|||Output: D2B(’decstring’) converts an argument string of optionallysigned decimal characters to a string of 32 ’0’ and ’1’ charactersrepresenting a bit string with the same binary value. The value ofdecstring must be representable as a 32-bit binary integer. A nullargument string returns a null string.ExamplesD2B(’’) has value ’’D2B(’0’) has value ’00000000000000000000000000000000’D2B(’+5’) has value ’00000000000000000000000000000101’D2B(’1022’) has value ’00000000000000000000001111111110’D2B(’-7’) has value ’11111111111111111111111111111001’D2C Format: Function-invocationOperands: Character372 HLASM: V1R6 Language RefOutput: D2C(’decstring’) converts an argument string of optionallysigned decimal characters to a string of four characters whose byte valuesrepresent the same binary value.
