Hi,
I have some questions about macros.
1/ I wonder how to count the number of variables in a macro.
I try the macro extended function (word count) but it doesn't work.
For example, if I have:
local myvars "var1 var2 var3 var4"
then `myvars' contains 4 variables.
But I do not know how to create a macro that contains the value 4.
2/ Suppose several datasets containing the same variable floor indexed
1, 2, 3, etc.... Floor* number varies with datasets.
I want to create the macro myfloor
local myfloor "floor*"
but then, I do not know how to create the macro containing the number of floor
as in question 1.
3/ How to work "inside" macros?
suppose you have the following: local "var1 var2 var3 .....varN"
suppose later in your dofile you want to do some tables on only - say 20-
variables of the macro.
Is it possible to just choose them (perhaps by specifying their position IN
the macro)
without creating other (sub)macros?
4/ Finally my last question is how to merge/append several datasets?
Suppose you have :
local mydata "data1 data2 data3 data4 data5"
foreach if i of local mydata {
foreach j of local mydata {
append `i' using `j'
}
}
How to avoid data1 being appended twice?
Best regards.
Amadou.
