e04nsc may be used to supply individual optional parameters to
e04nqc. The initialization function
e04npc must have been called before calling
e04nsc.
e04nsc may be used to supply values for optional parameters to
e04nqc. It is only necessary to call
e04nsc for those arguments whose values are to be different from their default values. One call to
e04nsc sets one argument value.
Each optional parameter is defined by a single character string,
consisting of one or more items. The items associated with a given option must be separated by spaces, or equals signs
. Alphabetic characters may be upper or lower case. The string
Print Level = 1
is an example of a string used to set an optional parameter. For each option the string contains one or more of the following items:
-
–a mandatory keyword;
-
–a phrase that qualifies the keyword;
-
–a number that specifies an Integer or double value. Such numbers may be up to contiguous characters
which can be read using C's d or g formats, terminated by a space if this is not the last item on the line.
For
e04nsc, each user-specified option is not normally printed as it is defined, but this printing may be turned on using the keyword
. Thus the statement
e04nsc ("List", &state, &fail);
turns on printing of this and subsequent options. Printing may be turned off again using the keyword
.
Optional parameter settings are preserved following a call to
e04nqc and so the keyword
is provided to allow you to reset all the optional parameters to their default values before a subsequent call to
e04nqc.
A complete list of optional parameters, their abbreviations, synonyms and default values is given in
Section 12 in
e04nqc.
None.
Not applicable.
e04nrc,
e04ntc or
e04nuc may also be used to supply optional parameters to
e04nqc.
