Problem description:
(Warning: This is a messy snippet)
What's in a file:
echo(Hello);
echo(World);
Here is my problem, the proc processes the first line and says Hello, but when it repeats to view the next line it stops at the var/command=copytext(file,src.linelength,findtext(file,"(")) code line.
What does the vars stand for:
linecount and linelength - This counts how many characters I've gone through in order to see what line I should be on next.
text - The text in between the echo brackets.
What it shows when I process the line:
Original Total Length: 1
File:
echo(Hello);
echo(World);
Command: echo
echo(Hello);
Total Length: 13
Computer Text: Hello
Original Total Length: 13
File:
echo(Hello);
echo(World);

In copytext(file,src.linelength,findtext(file,"("))
You didn't tell findtext to skip past the stuff already processed. So findtext returned the position of ( from the previous echo which is less than src.linelength the 2nd time around.
Try findtext(file,"(",src.linelength))
You'll need to do that all over the place.
Also, linecount is not giving you a count, but a text string.
