I'm reposting my previous hijacked thread on this subject. I am NOT interested in doing ANYTHING that SAS already knows how to do.
I may have asked this before I've been thinking about it for a long time.
Suppose I want to collect user input in the form of an array initialization. I want to use SAS to parse or expand the initialization e.g.
152 %let parm = (4*40 3*(3*7 8 9 10));
153 data _null_;
154 array parm[30];
155 retain parm &parm;
WARNING: Partial value initialization of the array parm.
156 put (parm
) (/=); 157 run;
parm1=40
parm2=40
parm3=40
parm4=40
parm5=7
parm6=7
parm7=7
parm8=8
parm9=9
parm10=10
parm11=7
parm12=7
parm13=7
parm14=8
parm15=9
parm16=10
parm17=7
parm18=7
parm19=7
parm20=8
parm21=9
parm22=10
parm23=.
parm24=.
parm25=.
parm26=.
parm27=.
parm28=.
parm29=.
parm30=.
As you can see SAS knows just what to do and give me exactly what I want. I just don't want the warning. I even works for character strings.
204 %let parm = (4*'hello kitty' 3*(3*('hello yourself')));
205 data _null_;
206 array parm[30] $32;
207 retain parm &parm;
WARNING: Partial value initialization of the array parm.
208 put (parm
) (/=); 209 run;
parm1=hello kitty
parm2=hello kitty
parm3=hello kitty
parm4=hello kitty
parm5=hello yourself
parm6=hello yourself
parm7=hello yourself
parm8=hello yourself
parm9=hello yourself
parm10=hello yourself
parm11=hello yourself
parm12=hello yourself
parm13=hello yourself
parm14=
parm15=
parm16=
parm17=
parm18=
parm19=
parm20=
parm21=
parm22=
parm23=
parm24=
parm25=
parm26=
parm27=
parm28=
parm29=
parm30=
The only way I can see to get rid of the warning it to know what the number of elements the "initialization list" is going to produce. But I ain't smart enough for that and why should I need to cause SAS knows already. I just don't want to be warned.
Perhaps another feature in SAS accepts the same "initialization list" syntax that doesn't produce the WARNING.
Did you look at the PARMS statement for GLIMMIX, VARIOGRAM etc? The syntax is a little different but if there is anyway to get it to generate the values and output them into a dataset then you could pull those values into a space delimited values to use for the ARRAY statement.
Proc POWER also has number lists. Perhaps this can be used to expand a list of values?
A number-list can be one of two things: a series of one or more numbers expressed in the form of one or more DOLISTs, or a missing value indicator (.).
The DOLIST format is the same as in the DATA step language. For example, for the one-sample test you can specify four scenarios (30, 50, 70, and 100) for a total sample size in any of the following ways.
NTOTAL = 30 50 70 100 NTOTAL = 30 to 70 by 20 100
A missing value identifies a parameter as the result parameter; it is valid only with options representing parameters you can solve for in a given analysis. For example, you can request a solution for NTOTAL:
NTOTAL = .
