Tip: See also the IDL_String::Compress method, which provides similar functionality but with an object-oriented interface.
The STRCOMPRESS function returns a copy of String with all whitespace (blanks and tabs) compressed to a single space or completely removed.
; Create a string variable S:
S = 'This is a string with spaces in it.'
; Print S with all of the whitespace removed:
PRINT, STRCOMPRESS(S, /REMOVE_ALL)
Result = STRCOMPRESS( String, /REMOVE_ALL )
The result is a compressed string.
The string to be compressed. If not of type string, it is converted using IDL’s default formatting rules. If String is an array, the result is an array with the same structure—each element contains a compressed copy of the corresponding element of String.
Set this keyword to remove all whitespace. Normally, all whitespace is compressed to a single space.
