Calcite | Level 5

I have a large text file with fixed columns that I need to import to SAS. The same file contains information at three levels: firms, associates and economic variables.

The first character of every observation tells wich level the values in the row are about (1 is about firms, 2 about associates...). According to the layout, each level has different variables of different lenghts.


This is a small example of the data I have to import. The first 4 variable are the same but afterwards each level has its own variables with different lenghts. The variable "type" identifies which level the observation is about. And all the other variables are bunched up in "other" and all the lines end with a "F":


        type $ 1-1
        full_registry $ 2-2
	type_update $ 3-3
	cnpj $ 4-17
	other $ 18-1200

I thought of two possibilities:

I. Read the txt three times with the three layouts for each level. Throw away the the observations that were read wrong. I'm not sure if this will work.


II. Read the first 4 variabels and put the rest of the line on a string variable, like I did in this example. Then use a bunch of substr() to separate the several variables. I'm not sure if this is the smartest way to do this.


Am I'm missing a much simpler way to do this?


I'm using Enterprise version 7.13.
