reading data in data step/input

hhchenfx — Wed, 05 Apr 2017 14:49:10 GMT

Hi Everyone,

I cannot get SAS read the datalines below correctly into SAS file.

The record 4 and 5 have blank or missing value.

Can anyone help me with that?

Thank you so much.

HHC

data F3_final_list;
input name $32. value;

datalines;
D_VR_comgap_stb_lb6_ord3_d2_x1	100
D_W_VR_comgap_lb10_stb_cd_xac123	2 
D_std90_gt_90	0
QD_VRcomgap_stb_lb10_ord3_d1_x	
DW_VRcomgap_stb_lb6_ord3_d1_y	
D_sys2_cnt_trend_prior	0
;run;

Please note that your data lines to not have a value for the value variable.

QD_VRcomgap_stb_lb10_ord3_d1_x

DW_VRcomgap_stb_lb6_ord3_d1_y

there is not second value on either of these lines.

Do you mean the dsd option:

data F3_final_list;
  infile datalines dsd;
  input name $32. value;
datalines;
D_VR_comgap_stb_lb6_ord3_d2_x1	100
D_W_VR_comgap_lb10_stb_cd_xac123	2 
D_std90_gt_90	0

The instruction $32. is incorrect. It tells SAS to read 32 characters, regardless of whether they are blanks or characters following blanks. A better way:

length name $ 32;

input name value;

Also, since some lines do not contain value, this statement belongs before the INPUT statement:

infile datalines truncover;

Because editors like EE, EG, SAS Studio are inconsistent with inline data, you may want stick with just one.
Line lengths, how blank lines are processed and '.' vary from editor to editor.
I like to stick with the 'old text editor', which was rock solid prior to 1984, but is deteriorating

In the old text editor
If you save this in your autocall library and turn on the command macros, 'options cmdmac;'


Hight light the cards data and type 'cuth' on the clean old text editor command line

%macro cuth/cmd;
 %do i=1 %to 20;
 c ' ' ' ' all;
 %end;
%mend cuth;

You can also use a function key ie 'F1 cuth'
