+
+## Data Input Alignment Fix (menages_corrected.sas)
+
+### Problem
+In the original code, the data values were not properly aligned, causing "karim" to start in the second column (Sexe) instead of the first column (Nom).
+
+### Original Problematic Code
+```sas
+Data menages_init;
+    length Nom $ 10;
+    input Nom $  Sexe $  Revenu Epargne Anciennete Statut_familial $;
+    list;
+    Cards;
+        karim H 38.5 5.9 10 marie
+        fatima F 31.2 3.8 6 celib 
+        ...
+;
+Run;
+```
+
+### Issues Identified
+1. **The `list;` statement**: This was incorrectly placed and not terminated properly
+2. **Indentation before data**: The data lines had leading spaces/tabs, which can cause misalignment
+3. **`Cards;` vs `Datalines;`**: While both work, `Datalines;` is the modern SAS syntax
+
+### Solution
+The corrected code removes the `list;` statement, uses `Datalines;`, and ensures all data starts at the beginning of each line without leading spaces:
+
+```sas
+Data menages_init;
+    length Nom $ 10;
+    input Nom $ Sexe $ Revenu Epargne Anciennete Statut_familial $;
+    Datalines;
+karim H 38.5 5.9 10 marie
+fatima F 31.2 3.8 6 celib 
+...
+;
+Run;
+```
+
+### Key Points for List Input in SAS
+- **List input** (default when using `$` and no column specifications) reads space-delimited values
+- Data should start at the beginning of lines to avoid parsing issues
+- Each value is read in order based on the INPUT statement
+- Character variables need the `$` modifier
+- No leading spaces should precede the first value on each data line
+
+### Expected Output
+The dataset `menages_init` will be created with 20 observations and the following variables:
+- **Nom**: Name (character, length 10)
+- **Sexe**: Gender (character)
+- **Revenu**: Revenue (numeric)
+- **Epargne**: Savings (numeric)
+- **Anciennete**: Seniority (numeric)
+- **Statut_familial**: Marital status (character)
+
+All values will be correctly aligned in their respective columns.

+   KEY CHANGES MADE:

+   
+   With list input (default when using $), SAS reads values separated by spaces.
+   The data should start at the beginning of the line to ensure proper alignment.
