The value part of the parameter statement is a string that conforms to command language rules (leading and trailing spaces are ignored; a backslash character at the end of a line may be used for continuation) and which can be interpreted by the user routine.

Standard utilities are provided for interpreting a parameter value as a simple Fortran-style INTEGER, REAL, DOUBLE PRECISION, or LOGICAL value, or as a CHAR string, or as a list of any of these types. These utilities expect list items to be separated by commas.

Note that these standard utilities do not support the processing of units.
