This routine sets a maximum value for the specified parameter. The value will be used as an upper limit for any value subsequently obtained for the parameter.

If the routine fails, any existing maximum value will be unset.

CALL PAR_MAXx( PARAM, VALUE, STATUS )

PARAM = CHARACTER$\ast$($\ast$) (Given)

VALUE = ? (Given)

STATUS = INTEGER (Given and Returned)

• There is a routine for each of the data types character, integer, real, and double precision: replace "x" in the routine name by C, I, R, or D respectively as appropriate. The VALUE argument must have the corresponding data type. If the parameter has a different type, the maximum value will be converted to the type of the parameter which must be character, double precision, integer, or real.

• If a minimum value has been set (using PAR_MINx) that is greater than the maximum at the time the parameter value is obtained, only values between the limits will not be permitted.

• The maximum value set by this routine overrides any upper RANGE value which may have been specified in the interface file. The specified value must not be outside any RANGE values. The maximum value may also be selected as the parameter value – again in preference to any upper RANGE value – by specifying MAX as the parameter value on the command line or in response to a prompt.
