Search an alpha field for a full stop

[LansaHelp]

Hi Guys,

I am looking to search an alpha field for the occurrence of a full stop (decimal point) character.

e.g. if the alpha field contains the value 'The amount is 123.45' then I'd like the search to return a Y. I have been looking to use SCANSTRING for this (I cannot use RDMLX). Any tips on how to make this work?

Scanstring works just fine:
Use Builtin(SCANSTRING) With_Args(#MYTEXT #CHECKS) To_Get(#STD_NUM)
