FORTRAN
integer*4 function strwid(str, length)
character*(*) str
integer*4 length

Pascal
function strwidth(str: pstring128): longint;

DESCRIPTION

strwidth returns the width of a text string in pixels, using the character spacing parameters of the current raster font.  strwidth is useful when you do a simple mapping from screen space to world space. 

Undefined characters have zero width. 

In FORTRAN, strwid has two arguments: str is the name of the string; length is the number of characters in that string.
