String handling in REXX.
In REXX programs, we can handle the string using inbuilt functions
1) LENGTH - It gives the length of given string.
Sample Program -
/*REXX*/
A = 'REXX'
B = LENGTH(A)
SAY 'Length of A is =' B
Console output -
Length of A is =4
2) WORD - It gives the number of words in the given string.
Sample Program -
/*REXX*/
X = 'Use of String function in REXX'
Y = LENGTH(X)
SAY 'No of words in X are =' Y
Console output -
'No of words in X are =6
