Find Character in Null-Terminated String (STRCHRNULL)

Bound program access
Built-in number for STRCHRNULL is 21.
STRCHRNULL (
            null_terminated_string   : address of aggregate(*)
            search_character         : signed binary(4) - rightmost byte
                                                   specifies the search
                                                   character  OR
                                       unsigned binary(1)  OR
                                       aggregate(1)
) :   space pointer(16) to the first character in the null-terminated string that
      matches the search character.  If the character is not found,
      null pointer value is returned

Description

The string specified by null terminated string is searched for the value specified by search character. The search terminates if the value is found or the null (ie. zero) character is reached. If the value is found, a space pointer to the character is returned. Otherwise, a null pointer value is returned.
