Hi guys,
I have tried to find a solution for this problem but couln't. If anyone of you have an Idea do help me.

INPUT_FILE

A5BNK723NVI - 1 - 294
A7QZM0VIT - 251 - 537
A7NU3411V - 245 - 527

I want an output file in which First column should have only fixed no. of characters say 7 or whatever no. I need and rest of the columns should be the same.

OUTPUT_FILE
A5BNK72 - 1 - 294
A7QZM0V - 251 - 537
A7NU341 - 245 - 527

Your help is highly appreciated. Smilie
