/NOSTANDARD Causes the compiler to generate messages whenever the compilation unit uses VSI Pascal language extensions, which are nonstandard Pascal features. See the "HP Pascal Language Reference Manual" for more information on standard Pascal features and the Pascal standards (ANSI, ISO, and Extended). The options are as follows: NONE Disables standards checking. ANSI Uses the rules of the ANSI standard (ANSI/IEEE770X3.97-1989). ISO Uses the rules of the ISO standard (ISO 7185-1989). EXTENDED Uses the rules of the Extended standard (ISO 10206-1989). [NO]VALIDATION Performs validation for the given standard. The /STANDARD qualifier allows you to use only two options. The first option selects the standard to be used (ANSI, ISO, or EXTENDED). The second option determines whether the "strict" validation rules are to be enforced, [NO]VALIDATION. Therefore, /STANDARD=(ANSI, ISO, VALIDATION) is not allowed since both ANSI and ISO are specified. By default, these information-level messages are written to the error file SYS$ERROR. Note that using the VALIDATION option changes all nonstandard information-level messages to error-level messages. The /STANDARD qualifier without options is equivalent to /STANDARD=(ANSI, NOVALIDATION). /STANDARD=VALIDATION is equivalent to /STANDARD=(ANSI,VALIDATION). The negation /NOSTANDARD is equivalent to /STANDARD=NONE.
