• MPRINT is effective only when MEXPAND is ON and is independent of the PRINTBACK<br />

subcommand.<br />

MITERATE and MNEST Subcommands<br />

MITERATE and MNEST control the maximum loop traversals and the maximum nesting levels<br />

permitted in macro expansions, respectively.<br />

• The specification on MITERATE or MNEST is a positive integer. The default for MITERATE<br />

is 1000. The default for MNEST is 50.<br />

BLANKS Subcommand<br />

BLANKS specifies the value that the program should use when it encounters a completely<br />

blank field for a numeric variable. By default, the program uses the system-missing value.<br />

• BLANKS controls only the translation of numeric fields. If a blank field is read with a string<br />

format, the resulting value is a blank.<br />

• The value specified on BLANKS is not automatically defined as a missing value.<br />

• The BLANKS specification applies to all numeric variables. You cannot use different specifications<br />

for different variables.<br />

• BLANKS must be specified before data are read. Otherwise, blanks in numeric fields are<br />

converted to the system-missing value (the default) as they are read.<br />

UNDEFINED Subcommand<br />

UNDEFINED controls whether the program displays a warning message when it encounters<br />

anything other than a number or a blank as the value for a numeric variable. The default is<br />

WARN.<br />

• Warning messages that are suppressed are still counted toward the maximum allowed<br />

before the session is terminated. To control the number of warnings (and therefore the<br />

number of invalid values) allowed in a session, use the MXWARNS subcommand.<br />

WARN Display a warning message when an invalid value is encountered for a<br />

numeric variable. This is the default.<br />

NOWARN Suppress warning messages for invalid values.<br />

MXERRS and MXWARNS Subcommands<br />

MXERRS and MXWARNS control the maximum number of error messages and warnings<br />

SPSS displays during one working session. The default for MXERRS is 40; the default for<br />

MXWARNS is 10.<br />

• Errors counted are those that cause SPSS to stop execution of a command but continue<br />

the session. MXERRS applies only to command files submitted for execution through
