Command Reference : String and Date Function Reference
Syntax: @wfindnc(str_list, str_cmp)
Argument 1: string list, str_list
Argument 2: string, str_cmp
Return: number n
Looks for the string str_cmp in the string list str_list, and returns the position in the list or 0 if the string is not in the list. This is the same as the @wfind function, but is not case-sensitive. Note that this function works only on single words; for multiple words, use @instr.
@wfindnc("I did it", "DID")
returns the number 2, indicating the caseless string “did” is second in the list.
@wfindnc("I did not do it", "i")
returns the number 1, since the first “i” or “I” encountered was in the first position.
See also @wfind, @instr.
