I have a file open -binary file as below:

Code:
open(unit=10,file=my_file_name,status='unknown',form='unformatted',
access='direct',recl=512*8)


The file needs to contain 512 words of 8 bytes each. Now I want to write few words forst as below:

!word_count_no is predefined


Code:
 write(10,rec=record_no)geom_data(word_count_no:512)


I get an error saying that a sub-string must be a character type.

Can anyone advise what is wrong?

How did you define the variable geom_data?

Perhaps you can use

Code:
write(10,rec=record_no)(geom_data(k),k=word_count_no,512)
