strwid, lstwid - returns the width of the specified text string
FORTRAN 77 SPECIFICATION
integer*4 function strwid(str, length)
character*(*) str
integer*4 length
integer*4 function lstwid(type, str, length)
integer*4 type
character*(*) str
integer*4 length
PARAMETERS
type expects the type of this string. See the man page for charstr
for a description of the type argument.
str expects the string to be measured.
length expects the number of characters in the string that is to be
measured.
