Hi SAS users!

I am doing some SAS homework and ran into this warning which won't let me convert character into numeric and therefore I am unable to run half this code. My goal is for prev_alive2 to be numeric and Ht_Inches to be numeric so I can calculate the BMI so I can have the BMI to look at mothers who are obese prior to pregnancy. Let me show you my code: and please let me know where I went wrong.

DATA LAB.STUDY_COHORT_2;
    FORMAT race_eth $30.;
    SET LAB.STUDY_COHORT;

    /* Gestational diabetes */
    IF RFDiabGest = "True" THEN GestDiab= "Y"; 
    ELSE GestDiab= "N";

    /* Race/Ethnicity variable */
    IF MatRace = " " OR MatEthnicity = " " THEN race_eth=" ";
    ELSE IF SUBSTR(MatEthnicity,1,1) = "2" THEN race_eth="Hispanic (any race)";
    ELSE IF SUBSTR(MatRace,2,1)="1" THEN race_eth = "Non-Hispanic White";
    ELSE race_eth="Non-Hispanic Non-White";

    /* Previous live births need to be converted to numeric variable */
   prev_alive2 = INPUT(PREV_ALIVE, 2.);
   IF PREV_ALIVE= . THEN PREV_ALIVE = .;

    /* Convert mother's height to height in inches */
    IF MotherHeight= . THEN Ht_inches = .; 
    ELSE Ht_inches=(INPUT(SUBSTR(MotherHeight,2,1),1.)*12)+(INPUT(SUBSTR(MotherHeight,4,2),2.));

    /* Convert prior weight to a numeric variable */
    IF priorweight = . THEN priorweight2 = .; /* Set to missing if unknown */
    ELSE priorweight2= INPUT(priorweight,4.);

    /* Calculate BMI */
    IF priorweight2= . or Ht_inches= . THEN BMI = .; /* Set to missing if height or weight is missing */
    ELSE BMI = ((priorweight2)/(Ht_inches**2))*703;

    /* Categorize into Obese status */
    IF BMI = . THEN ObesePrior = " "; /* Set to missing if BMI is missing */
    ELSE IF BMI < 30 THEN ObesePrior = "N";
    ELSE ObesePrior = "Y";

    /* Variable for preterm birth */
    IF EstGest > 36 THEN Preterm = "N"; 
    ELSE Preterm = "Y";
    
    /* Labeling new variables */
    LABEL GestDiab = "Gestational Diabetes"
          race_eth = "Race/Ethnicity"
          prev_alive2 = "Previous Live Births"
          Ht_inches = "Mother's Height (in inches)"
          priorweight2 = "Prior Weight Before Pregnancy"
          BMI = "Body Mass Index"
          ObesePrior = "Obese Prior (Y/N)"
          Preterm = "Gestation Age Before 37 Weeks";
RUN;

The dataset looks like this:

Re: WARNING: Limit set by ERRORS= option reached. Further errors of this type will not be printed.

The error is caused by attempting to compare a character value (MotherHeight) to a numeric MISSING value (.) in this line of code:

/* Convert mother's height to height in inches */ IF MotherHeight= . THEN Ht_inches = .;

Using the MISSING function will resolve the problem:

/* Convert mother's height to height in inches */ IF MISSING(MotherHeight) THEN Ht_inches = .;
