[TIP] CTRAN without pain
I thought I'd make a separate post about this.

You can use CTRAN without having to figure out the Hex value (which is different for ASCII and EBCDIC) by incorporating the BYTVAL function into the code:

Original syntax:
CTRAN(charlen, string, decimal, decvalue, outfield);

BYTVAL(character, outfield);

Adapted syntax:
CTRAN(charlen, string, BYTVAL('from','I3'), BYTVAL('to','I3'), outfield);

e.g.:
-*-- Convert Apostrophe to Right Single Quotation Mark -------------------------
-SET &OBJ_NAME4 = CTRAN(&OBJ_NAME.LENGTH, &OBJ_NAME, BYTVAL('''','I3'), BYTVAL('’','I3'), 'A&OBJ_NAME.LENGTH');
-*-- Convert Slash and Dash to blank -------------------------------------------
RGN1/A50 = CTRAN(50, RGN0, BYTVAL('/','I2'), BYTVAL(' ','I2'), 'A50');
RGN2/A50 = CTRAN(50, RGN1, BYTVAL('-','I2'), BYTVAL(' ','I2'), 'A50');

You never have to look for an ASCII or EBCDIC chart again!

Very nice indeed Francis. I'll make sure to take note of the tip (a bookmark on this topic would be better, of course Wink )

That is great. Cross Platform.

The only issue is when you want to CTRAN a non printable.

It's not an issue - you can use CTRAN in it's usual form for that.

I think Waz's point is that with non-printable characters you still have to look up the code in and ASCII or EBCDIC manual (unless you have them memorized).

This is a great tip. Probably why I never thought of it. Smiler

Interesting that HEXBYT behaves properly even when the fex source is in Unicode.

Apparently 16-bit Unicode source is mapped to 8-bit (ASCII) coding before dialog manager sees it, and that's how the Focus code is placed in FOCSTACK for execution.

-- But what does the mapping do with non-Latin Unicode values?

I was only pointing out that if you wanted to CTRAN a character to, say, a carriage return, you would have to go with the number.

Bonjour Francis,

I have a field in a table which contains this value : "100-130-150-200-250 €".
In excel the field appears as "100-130-150-200-250 ¤" (euro sign is not converted properly).
How can I use your example to keep the euro sign in excel ?

Thanks for your help.
Catherine

That is probably related to your NLS values. There have been other recent posts on that.

is this field always in the same format?
numbers and dash at the same place?

If i would suggest some other solution

something like

NEWFORMAT1/A15=EDIT(OLDFIELD,'999$999$999$999$999$$');
-* this wil give you the string without dashes and valuta code
NEWFORMAT2/D15=EDIT(NEWFORMAT1);


now your newformat2 field is a number and you can present it with any valuta code, and that might work in excel as it should (although the NLS remark might still be important)
