Compare strings and data strings (continued)

Abstr:True. If <F2> belongs to type C, you can use the following wildcard characters in <F2>: _ * For any string _ + for any single character to ignore trailing spaces and be case insensitive. If the comparison result is true, the system word...

True. If <F2> belongs to type C, you can use the following wildcards in <F2>: _ * Used for any character string _ + Is used for any single character Ignore trailing null cells and compare them case insensitive. If the comparison result is true, the system field SY-FDPOS contains <F2> Offset in <F1>. If false, the SY-FDPOS contains the length of <F1>. If you want to compare the special characters in <F2>, put the character # in front of it. You can use another code. Character # specify _ Font characters _ Wildcard "*" (input #*) _ Wildcard "+" (input # +) _ Changing the code symbol itself (input ##) _ Space at the end of the string (input #___) NP (does not contain a pattern) If <F1> does not contain mode <F2>, the logical expression <F1> NP <F2> True. In <F2>, you can use the same wildcard character and codeword character as CP. Ignore trailing null cells and compare them case insensitive. If the comparison result is true, the system field SY-FDPOS contains The length of <F1>., if the result is false, the offset of the SY-FDPOS containing <F2> in <F1>. Data: F1 (5) Type C value <F1>, F2 (5) Type C value <F2>. If F1 <operator> F2. Write:/'comparison true, SY-FDPOS =', SY-FDPOS. Else. Write:/'comparison false, SY-FDPOS =', SY-FDPOS. Endif. The following table lists the execution results of the program, depending on the operator used and the F1/F2 field. <F1> <operator> <F2> results SY-FDPOS 'Bd 'co' abcd' true 5 'Bd 'co' abcde' false 2 'Abc12 'cn 'abcd' true 3 'Ababc' CN 'abcd' False 5 'Abcde' ca 'bd 'true 1 'Abcde' ca'bd 'False 5 'Abab' na 'AB' false 0 'Ababa 'A' AB 'true 5 'Abcde' CS 'bc' Zhen 1 'Abcde' CS 'ce 'False 5 'Abcde' NS 'bc' false 1 'Abcde' NS 'ce 'true 5 'Abcde' CP '* B *' true 1 'Abcde' CP '* # B *' False 5 'Abcde' NP '* B *' false 1 'Abcde' NP '* # B *' true 5

Next tip:To compare strings and data strings, you must compare strings (type C) and numeric text (Type N). You can use the following operators in logical expressions. <Operator> meaning CO only contains CN not only contains Ca contains any NA Not contains any CS contain string NS not contain string CP contains mode NP...
