README.str

The str_* routines perform a number of useful operations on strings.

integer functions
=================================================================
strlen(str)
   This returns the length of the string as it appears to a human (i.e.
   it returns the location of the last non-space character).  0 is returned
   if the string doesn't contain any non-blank characters.
findex(string,substring)
fcindex(string,char)
fclindex(string,charlist)
   Return the position of the first occurence of substring, char, or
   any of the characters in charlist in string respectively.  If no
   occurence is found, 0 is returned.
lindex(string,substring)
lcindex(string,char)
lclindex(string,charlist)
   Return the position of the last occurence.
nindex(string,substring,ind)
ncindex(string,char,ind)
nclindex(string,charlist,ind)
   Returns the position of the next occurence AFTER postion ind.  If
   ind=0, the search starts at the start of the string.  If ind is
   greater than the length of the string, 0 is returned.
pindex(string,substring,ind)
pcindex(string,char,ind)
pclindex(string,charlist,ind)
   Returns the position of the previous occurence BEFORE position.  If
   ind=0 or ind is greater than the length of the string, the search
   starts at the end of the string.
fncindex(string,char)
fnclindex(string,charlist)
lncindex(string,char)
lnclindex(string,charlist)
nncindex(string,char,index)
nnclindex(string,charlist,index)
pncindex(string,char,index)
pnclindex(string,charlist,index)
   Return the positions of the occurences that are NOT the character
   or one of the characters in the character list.

logical functions
=================================================================
streq(str1,str2,insensitive)
   This returns .true. if str1 and str2 are equal.  The comparison can
   be case insensitive.

subroutines
=================================================================
upcase(str)
   This function converts str to all uppercase.
delspc (instr, outstr)
   This strips all the spaces and tabs from instr.  The resulting string
   is returned as outstr (both instr and outstr may be the same string
   in the calling program).
