How do I convert a string to an enum?

U need to check enum.descr$ function for each enum option and compare the string with string input . If it matches case insensitive , the option is the enum number . U can use RDI functions for this entire function.

You use
ltoe(val(YOURSTRING)))

You use
ltoe(val(YOURSTRING)))only in case your "text" has the form of "tcyesno.no" for value (text) "No" (enum.descr$). When you want to start with the "No" word you need more code, to find the enum descriptions for the field, put them in an array, compare the input string with the stored values (may be all to.upper$) and use the array index as the value for ltoe(). But be aware that you should do this for all used languages, because the "tcyesno.no" is language independent, the "No" part is not.
