I need help with SAS coding

Extend the code in Step $6$ by adding six more IF$-$THEN sets of statements to check for disease $($dx$1-$dx$10)$ value ranges and create the other six indicators, DXGRP$1,$ DXGRP$2,$ DXGRP$3,$ DXGRP$4,$ DXGRP$5,$ DXGRP$6,$ DXGRP$7.$

Your final data set, STEP$6,$ should have PATID and the seven DXGRP# indicators.

DX values DXGRP DESCRIPTION

$-------------------------------$

$331($pertussis$/$whooping cough$)$

$752($infectious mononucleosis$)$

$90-993($syphilis and other venereal diseases: STDs$)$

$4104($myocardial infarction$)$

$430-4385($cerebovascular disease$)$

$403-46($chronic kidney disease$)$

$585-66($chronic kidney disease$)$

$638-96($chronic kidney disease$)$

$4627($acute sore throat$)$

Keep only PATID DXGRP$1-$DXGRP$7.$

Don't forget to output your processing after the DO$/$END loop.

Finally, add a LABEL statement to add variable labels as follows

DX values DXGRP DESCRIPTION

$-------------------------------$

DXGRP$1$ pertussis$/$whooping cough

DXGRP$2$ infectious mononucleosis

DXGRP$3$ syphilis and other STDs

DXGRP$4$ myocardial infarction

DXGRP$5$ cerebovascular disease

DXGRP$6$ chronic kidney disease

DXGRP$7$ acute sore throat

These tasks will complete the DATA step.

Then, use a PROC FREQ to show the frequency of DXGRP$1$ through DXGRP$7$ as

DXGRP$1,$ DXGRP$2$ and DXGRP$7$ are all zero frequency.

DXGRP$3$ appears as in Steps $4$ and $5.$

DXGRP$4$: Value $1$ appears in three observations.

DXGRP$5$:

Value Frequency

$089$

$110$

$21$

DXGRP$6$: Value $1$ appears in three observations

All variable labels should appear in the output tables!
