Try with Regex - [áéíóú] and replacement á.

Use program DEMO_REGEX_TOY to play with it.

If the input text is -

Thís hás sómé néw stúff

Output would be (with replace all)

Thás hás sámá náw stáff

Thaks, I can put multiple values in WITH 'x'?

[naimesh_patel]

Yes. You need to put as many characters as you want.

Thanks! Like:<br>

REPLACE ALL OCCURRENCES OF REGEX 'áéíóú' IN my_var WITH 'param1' 'param2' 'param3...?

Since you want to work on the same field a lot, I'd suggest a local macro (this is an example where a macro makes sense):

define m_rep.

REPLACE ALL OCCURRENCES OF &2 IN &1 WITH &3.

end-of-definition.

(note the sequence of placeholders)

Now you can code like so.

m_rep fieldname:

'from1' 'to1',

'from2' 'to2',

'from3' 'to3'.

With proper naming and indentation, it makes your code more readable. The performance is the same of course... Keep the macro close to the code if possible.

If the action is more complex and you need to debug, you can use the same technique for readability and issue a perform from the macro. I only use macros for some cases, and this would be one of them.

These are HTML tags. I'm fairly sure there are some standard function modules or methods that do this work for you. Or perhaps the escape string function (7.40).
