/sys$common/syshlp/SDA.HLB  —  EVALUATE
    Computes and displays the value of the specified expression in
    both hexadecimal and decimal. Alternative evaluations of the
    expression are available with the use of the qualifiers defined
    for this command.

    If the expression is equal to the value of a symbol in the SDA
    symbol table, that symbol is displayed. If no symbol with this
    value is known, the next lower-valued symbol is displayed with an
    appropriate offset unless the offset is extremely large.

    Format

                | /ISR | /PFS | /PS | /PSR

1  –  Parameter 

 expression

    SDA expression to be evaluated. Type HELP EXPRESSIONS for a
    description of the components of SDA expressions.

2  –  Qualifiers

2.1    /CONDITION_VALUE 

    Displays the message that the $GETMSG system service obtains for
    the value of the expression.

2.2    /FPSR 

    (Integrity servers only) Evaluates the specified expression in
    the format of a floating-point status register.

2.3    /IFS 

    (Integrity servers only) Evaluates the specified expression in
    the format of an interruption function state.

2.4    /ISR 

    (Integrity servers only) Evaluates the specified expression in
    the format of an interruption status register.

2.5    /PFS 

    (Integrity servers only) Evaluates the specified expression in
    the format of a previous function state.

2.6    /PS 

    Evaluates the specified expression in the format of a processor
    status.

2.7    /PSR 

    (Integrity servers only) Evaluates the specified expression in
    the format of a processor status register.

2.8    /PTE 

    Interprets and displays the expression as a page table entry
    (PTE). The individual fields of the PTE are separated and an
    overall description of the PTE's type is provided.

2.9    /SYMBOLS 

       /SYMBOLS[=filter]
       /NOSYMBOLS

    The default behavior of the EVALUATE command is to display up
    to five symbols that are known to be equal to the evaluated
    expression. If /SYMBOLS is specified with no filter, all symbols
    are listed in alphabetical order. If /NOSYMBOLS is specified,
    only the hexadecimal and decimal values are displayed. If
    /SYMBOLS is specified with a filter, only symbols that match
    the filter are displayed. The filter is a string containing
    wildcards, such as PCB$*.

2.10    /TIME 

    Interprets and displays the expression as a 64-bit time value.
    Positive values are interpreted as absolute time; negative values
    are interpreted as delta time.
