Is there a way to use printf and a format code which takes as a
parameter a variable size
width that is calculated prior to calling printf.
Reason why: So that the output file will have pretty formatted
columns.

For example,
Suppose I have a program that prompts for a string.
The program doesnt know ahead of time how long the string will be.

Then I use strlen to find its length
len=strlen(word)

can I do something like the following:

printf,1,word,format='(alen)'
