Modules

	This module defines functions to manipulate strings of characters. Description.

Functions/Subroutines
pure character(len=:) function, allocatable, public	upper (s)
	Returns a copy of the string converted to uppercase.
pure character(len=:) function, allocatable, public	lower (s)
	Returns a copy of the string converted to lowercase.
pure character(len=:) function, allocatable, public	swapcase (s)
	Return str with case of letters swapped.
pure character(len=:) function, allocatable, public	reverse (s)
	Reverse a string.
pure logical function, public	endswith (s, suffix)
	Return True if S starts with the specified prefix, False otherwise.
pure logical function, public	startswith (s, prefix)
	Return True if S starts with the specified prefix, False otherwise.
pure character(len=:) function, allocatable, public	lstrip (s, chars)
	This function returns a copy of the string with leading chars removed.
pure character(len=:) function, allocatable, public	rstrip (s, chars)
	This function returns a copy of the string with trailing chars removed.
pure character(len=:) function, allocatable, public	strip (s, chars)
	This function returns a copy of the string with leading and trailing chars removed.
pure integer function	count_sub (s, sub, start, end)
	Return the number of occurrences of substring sub in string S[start:end].
pure logical function, public	issub (s, sub)
	Returns .True. if sub is present in S, .False. otherwise.
pure character(len=:) function, allocatable, public	rjust (s, width, fillchar)
	Returns a right-justified string of length width.
pure character(len=:) function, allocatable, public	ljust (s, width, fillchar)
	Returns a left-justified string of length width.
pure character(len=:) function, allocatable, public	zfill (s, width)
	Pad a string with zeroes ("0") to specified width. If width is <= input string width, then the original string is returned.
character(len=:) function, allocatable, public	center (s, width, fillchar)
	Center a string to a specified width. The default character to fill in the centered string is a blank character.
integer function, public	find (s, sub, start, end)
	Return the lowest index in S where substring sub is found.
character(len=:) function, allocatable, public	replace (s, old, new, count)
	Return a copy with all occurrences of substring old replaced by new.
integer function, public	str2i (s_in)
character(len=:) function, allocatable	z2str (zin)
	z2str gives a string representation of a complex number
function	zarr2str (vec)
function	dparr2str (vec)
function	rarr2str (vec)
function	iarr2str (vec)
character(len=:) function, allocatable	dparr2d2str (vec)
character(len=:) function, allocatable	rarr2d2str (vec)
character(len=:) function, allocatable	iarr2d2str (vec)
character(len=:) function, allocatable	zarr2d2str (vec)
