Dear All

Please check your small guns arsenals for existing function which can filter string and allow only
predefined subsets of ascii scale. I want to alow only numbers, letters and limited number of other characters.
(To clean up those pesky special chars out of imported excel content)

Something like;

function SubAsci
lParameters cAnyString,cAllowOnlySequence
.
. 
.
return cFilteredString

I expect no less then 3 ready made functions that already do this (+few extras), from seasoned club of gunners like yourselves ;-))

Thank you in advance!
Sergio
