The STRJOIN function collapses a one-dimensional string array into a single merged string or two-dimensional string array into a one-dimensional array of merged strings. The strings in the removed first dimension are concatenated into a single string using the string in Delimiter to separate them.
Examples
Replace all the blanks in a sentence with colons:
str = 'Out, damned spot! Out I say!'
print, (STRJOIN(STRSPLIT(str, /EXTRACT), ':'))
IDL prints:
Out,:damned:spot!:Out:I:say!
Syntax
Result = STRJOIN( String [, Delimiter] [, /SINGLE] )
Return Value
Returns the merged strings.
Arguments
String
A string array to be collapsed into merged strings.
Delimiter
The separator string to use between the joined strings. If Delimiter is not specified, an empty string is used.
Keywords
SINGLE
If SINGLE is set, the entire String is joined into a single scalar string result.
