yotam_k Deleted Jan 12, 2001, 3:46 AM Post #1 of 7 (1318 views) Help In Cutting A String.... Can't Post Lets Say i have a text , article , that I load it from a file , the text contains Plain text . I need to cutt each line in the text after 40 Charcters in the line and then transfer it to the next line and then cut The next line by the same messurments (after 40 Char.) [ all this content should be of course , in a Integral (with $ sign...) ] . I need this for adding this text into a thin table space . I know that there is a Cammand in perl that does it Which I think it beeing called SUBSTRING but i realy dont know it's syntex and that whay I'm Asking . If I didn't simplfy my question : " Could someone tell me the syntex SUBSTRING to cut the first 40 Charcters From the Integral "$string" ? thank you all !!!!!!!!

[In reply to] Can't Post Yotem_k, the syntax for the substring is as follows: $var= substr("$string", starting position, length of cutout); so from what i am gathering you would need something like this: $var= substr("$string", 40); #if you leave the last number off it will by default return all from that point on. print "$var\n"; i hope this clears it up for you.

[In reply to] Can't Post But I have one more question to deep my knowlge : you said that : $var= substr("$string", starting position, length of cutout); so if i want to cutt from the 28 char. I should write : $var= substr("$string", 28 , 40); ? And thank you again. Yotam.

[In reply to] Can't Post $var= substr("$string", 28 , 40); that will cut from the 28th character to the 40th, if you want to cut everything from the 28th on use this: $var= substr("$string", 28); glad i could help:)

You were right when you said the third argument is the length of the substr. It cuts from the 28th to the 67th, which is 40 characters.
