Could
we apply
CHRTRAN(?) Function
?
Replaces each character in a character expression that matches a character in
a second character expression with the corresponding character in a third
character expression. CHRTRAN(cSearchedExpression, cSearchExpression, cReplacementExpression)
Return Values
Character
Parameters
- cSearchedExpression
- Specifies the expression in which CHRTRAN(?) replaces
characters.
- cSearchExpression
- Specifies the expression containing the characters CHRTRAN(?)
looks for in cSearchedExpression.
- cReplacementExpression
- Specifies the expression containing the replacement characters.
If a character in cSearchExpression is found in
cSearchedExpression, the character in cSearchedExpression is
replaced by a character from cReplacementExpression that's in the same
position in cReplacementExpression as the respective character in
cSearchExpression.
If cReplacementExpression has fewer characters than
cSearchExpression, the additional characters in
cSearchExpression are deleted from cSearchedExpression. If
cReplacementExpression has more characters than
cSearchExpression, the additional characters in
cReplacementExpression are ignored.
Remarks
CHRTRAN(?) translates the character expression
cSearchedExpression using the translation expressions
cSearchExpression and cReplacementExpression and returns the
resulting character string.
Example? CHRTRAN('ABCDEF', 'ACE', 'XYZ') && Displays XBYDZF
? CHRTRAN('ABCD', 'ABC', 'YZ') && Displays YZD
? CHRTRAN('ABCDEF', 'ACE', 'XYZQRST') && Displays XBYDZF

Well, I had no clue
of its existence.?
Certainly you could
use regular exprs to do the same thing, but in some situations the LIKE
function could save the hassle of instantiating a regex
object.
?
LIKE(cExpression1, cExpression2)
Return
Values
Logical
Parameters
cExpression1
Specifies
the character expression that LIKE(?) compares with cExpression2. cExpression1 can contain the wildcards
such as * and ?. The question mark (?) matches any single character
in cExpression2 and the
asterisk (*) matches any number of characters. You can mix any number of
wildcards in any combination in cExpression1.
cExpression2
Specifies
the character expression LIKE(?) compares with cExpression1. cExpression2 must match cExpression1 letter for letter in order
for LIKE(?) to return true
(.T.).

Eric -?It's had
it, like, forever. It's in my FoxPro 2.6 language reference manual (remember
manuals?), copyright 1993. Good morning, Rip Van Winkle!
If it makes you feel
any better, it's not mentioned in my dBase III Plus
manuals.
Seems like?this
should be something to do?using Regular Expressions,
eh?

Ok, I'm still looking for the previous function, and
am probably gonna roll my own, but when did VFP get the Like()
function?? That's cool!
