Using a string variable as a filename

[Alan Slavin]

How do I create a filename from a string variable, or where do find this in the manual? 

 

For example, in the following I want to save a graph with the filename "graph14" of .eps type.  However, it saves the graph under the filename graph.eps. 

 

 graph=strcat("graph", "14")
 print -deps graph.eps

Neither of the following works either

 

print -deps "graph".eps

 

graph=strcat("graph", "14", ".eps")
 print -deps graph

Thanks.
