SCAN opcode example is given below. The first parameter must be of type character, graphic, or UCS-2, fixed or varying length. As with all BIFs, one of the major advantages compared with the old op-code version is that the BIF can be used directly in a conditional expression–no need to create a temporary work The first is that with %CHECK, the compare string is treated as a list of individual characters, whereas %SCAN operates on it as a single string. ) The DSPLY op-code will output the first characters that don't match.
