This is the treasure of this web site. I really grateful to all your's help. I came across good knowledgeble hints. I am seeing such type of code from IBM platform. Only some source code files having such problem ending with line numbers. I unable to apply this technique on every file because of the following. For ex:

/* Developed in 1997
by some xxxx */
#define m 100   100020
#define n 2000  100040
[download]

The logic will eat 1997 & 100 & 2000 in the above code. I unable to come with a regular expression in a single line. But alleast it tells me which programs having such problem to note down. I am editing those programs in a text editor using vertical block mode editing and deleting those numbers before compiling. I thought it works with a single line regular expression. But it looks I need to go for a script to add more conditions. I appreciate your help. Thanks Ashok
