Oh boy,

FUNC HexString2String(cHex AS STRING) AS STRING
LOCAL cRes AS STRING
LOCAL i, nVal AS INT
IF SLen(cHex) >=2
FOR i := 1 UPTO SLen(cHex)-2 STEP 3
nVal := 16*Val(SubStr3(cHex,i,1))+Val(SubStr3(cHex,i+1,1))
? cRes += CHR(nVal)
NEXT
ELSE
cRes := ""
? "Param invalid"
ENDIF
RETURN cRes

But better probably:
FUNC HexString2String(cHex AS STRING) AS STRING
RETURN Hex2C(StrTran(cHex, " ", ""))

enough...

IIRC it's in VO25Lib, either that or I converted a Clipper function 10+
years ago<g>

Brilliant, many thanks that HexString2String work fine.

Just wondering.

Hex2C() is not documented in the Help file.
Did GrafX just forget it to document or is it a unsupported function (and
shouldn't be used) ?

How do you guys find out about this stuff (did it used to be a clipper
function) ?

Greetings,
Jack

make a repo and import the sdk files - there are many, many goodies
hidden ;-)
