Transcribed Image Text:### Program to Eliminate Blanks from a String in Memory
A string of ten data bytes is stored in memory locations starting at XX50H. The string includes some blanks (bytes with zero value). Your task is to write a program to eliminate the blanks from the string.
**Steps to Approach the Problem:**
1. **Identify and Analyze the Memory Block:**
- Memory locations start from XX50H and contain a sequence of ten bytes.
- Among these bytes, some are blank (represented as zero).
2. **Program Objective:**
- Remove the zero-value bytes from the given memory locations.
- Keep the remaining non-zero bytes contiguous.
3. **Implementation Strategy:**
- Traverse each byte starting from XX50H.
- Check if the current byte contains a zero value.
- If a zero-value byte is found, shift all subsequent non-zero bytes one position to the left.
- Continue the process until all zero-value bytes are eliminated.
4. **Expected Outcome:**
- A new string, devoid of zero-value bytes, stored in the same starting memory location.
By following these guidelines, you can successfully write a program to process and clean the string data as required.
