Variations of string search

[Former Member]

Hi SDN,

Re: IF Var1 CP 'HELLO'

Can someone direct me to a source to find out variations of CP (Contains Pattern)?

Also, how would you check if a string contains four numbers following a letter?

Thanks for your help.

CP (Contains Pattern):

The complete string c1 matches the pattern c2 (c1 "matches" c2).

The pattern c2 can contain ordinary characters and wildcards.

'*' stands for any character string and '+' denotes any character.

If the result of the comparison is positive, the system field SY-FDPOS contains the offset of the first character of c2 in c1. The wildcard character '*' at the beginning of the pattern c2 is ignored when determining the value of SY-FDPOS.

If the result of the comparison is negative, the system field SY-FDPOS contains the length of c1.

Examples:

'ABCDE' CP 'CD' is true; SY-FDPOS = 2.

'ABCDE' CP '*CD' is false; SY-FDPOS = 5.

'ABCDE' CP '+CD' is true; SY-FDPOS = 0.

'ABCDE' CP '+CD*' is false; SY-FDPOS = 5.

'ABCDE' CP 'BD*' is true; SY-FDPOS = 1.

The character '#' has a special meaning. It serves as an escape symbol and indicates that the very next character should be compared "exactly".

This allows you to search for:

- characters in upper or lower case

e.g.: c1 CP '#A#b'

- the wildcard characters '*', '+' themselves

e.g.: c1 CP '#' or c1 CP '#+*'

- the escape symbol itself

e.g.: c1 CP '##'

- blanks at the end of c1

e.g.: c1 CP '*# '

If c2 does not contain the wildcard character '*', the shorter field is padded with "soft blanks" to bring it up to the length of the longer field.

Examples:

'ABC' CP 'ABC ' is true,

'ABC ' CP 'ABC' is true,

but

'ABC' CP 'ABC+' is false,

'ABC' CP 'ABC# ' is false,

because a "soft blank" is neither any character ('+') nor a "real" blank ('# ').

The escape symbol does not affect the length of f2 ('A#a#B' still has the length 3).

The comparison is not case-sensitive.

Sudhir,

Thanks for the help. I actually was looking for other constrcts like CP and not more examples of CP.

Thanks.
