hi
my program has 3 error! i don't understad where is the error
my main problem is in line 636. the "ds" variable has error and i don't know why!!!
and there are 2 error for overflow in lines 281 and 263 .
you can change the "E50 TO E35" and it seems the error was correct but i don't know whether it cause change to main output or not.
the out put must be in 10 page but my output is in 9 line . i know that the variable "I3" is page number of output.
please view my program and tell me if you can help!
thanks

rather than commenting the errors, could you provide a strict copy of the messages please ?

About the variable DS line 636, I observe that the first significant character is written in column two. As you are using the fixed FORTRAN format (source suffix .f), then each line must start in column 7 (except continuing lines in column 6 and labels in columns 1-6)
