Input String. A character string to translate.
Search Pattern. A character string as the same length as input string containing characters likely and unlikely to match Input_String.
Replace Pattern. A character string as the same length as Input_String containing the characters to substitute when a character in Search_Pattern matches a character in Input_String.
Replaces a portion of one string with another.
CHRTRAN() returns a character string where characters in string_1 that match those in string_2 have been replaced with characters in the same position in string_3. Case sensitive. Common uses include changing character values within either a global update or an append operation. CHRTRAN() is especially useful for blanking specific positions in fields and for changing formatting characters used within a character code.
chrtran( "(617)229-2924" , "(XXX)XXX-XXXX" , " XXX XXX-XXXX" ) -> " 617 229-2924" chrtran( "AaBbCcDd" , "XXBXXXXX" , "XXbXXXXX" ) -> "AabbCcDd"
Assume the HOMEPHONE field contains values such as "(102)345-6789" and "(304)567-8901". In the following expression, since only the parentheses specified in string_2 match any values in HOMEPHONE, CHRTRAN() forms values using all the other characters from a HOMEPHONE value, plus the spaces included in the first and fifth position from string_3.
chrtran(HOMEPHONE, "(AAA)AAA-AAAA", " AAA AAA-AAAA")
For the records containing the values listed above, CHRTRAN() returns " 102 345-6789" and " 304 567-8901".
