Using UPPER

Specifying UPPER on any of the PARSE instructions converts characters to uppercase (lowercase a–z to uppercase A–Z) before parsing. The following table summarizes the effect of the parsing instructions on case.

Converts alphabetic characters to uppercase before parsing	Maintains alphabetic characters in case entered
ARG PARSE UPPER ARG	PARSE ARG
PARSE UPPER EXTERNAL	PARSE EXTERNAL
PARSE UPPER NUMERIC	PARSE NUMERIC
PULL PARSE UPPER PULL	PARSE PULL
PARSE UPPER SOURCE	PARSE SOURCE
PARSE UPPER VALUE	PARSE VALUE
PARSE UPPER VAR	PARSE VAR
PARSE UPPER VERSION	PARSE VERSION

The ARG instruction is simply a short form of PARSE UPPER ARG. The PULL instruction is simply a short form of PARSE UPPER PULL. If you do not desire uppercase translation, use PARSE ARG (instead of ARG or PARSE UPPER ARG) and use PARSE PULL (instead of PULL or PARSE UPPER PULL).
