STRCOMPRESS Function

Compresses the white space in an input string.

result = STRCOMPRESS(string)

string The string to be compressed.

result A string with all white space (blank spaces and tabs) compressed to a single space or completely removed. If string is an array, the result is an array with the same structureeach element contains a compressed copy of the corresponding element of string.

Remove_All If nonzero, removes all white space. Otherwise, all white space is compressed to a single space (the default).

If not of type string, string is converted to string using the default formatting rules of PV-WAVE. (These rules are described in Free Format Output in Chapter 8 of the PV-WAVE Programmer's Guide.)

In this example, STRCOMPRESS is used to remove the excess white space in a string.

s = ' This string   has     extra white space'

; Create a string with excess white space characters.

PRINT, STRCOMPRESS(s)

; Display the string with all excess white space removed.

This string has extra white space

This example uses STRCOMPRESS to remove all white space from each element of a three-element string array.

s = strarr(3)

; Create a three-element string array.

s(0) = 'a      b  c'
s(1) = '   d    e f'
s(2) = 'g     h    i'

; Assign a string to each element of the array.

PRINT, TRANSPOSE(STRCOMPRESS(s, /Remove_All))

abc
def
ghi

; Remove all spaces from each element of the array and display 

; the resulting array. TRANSPOSE is used to display the array as 

; a column vector.
