Returns a substring that has a length you specify, using blank padding if necessary
Category: Character
SUBPAD ( string , position <, length >)
string
specifies a character string.
position
is a positive integer that specifies the position of the first character in the substring.
length
is a non-negative integer that specifies the length of the substring. If you do not specify length , the SUBPAD function returns the substring that extends from the position that you specify to the end of the string.
If the SUBPAD function returns a value to a variable that has not yet been assigned a length, by default the variable is assigned a length of 200.
If the substring that you specify extends beyond the length of the string, the result is padded with blanks.
The SUBPAD function is similar to the SUBSTR function except for the following differences:
If the value of length in SUBPAD is zero, SUBPAD returns a zero-length string. If the value of length in SUBSTR is zero, SUBSTR
writes a note to the log stating that the third argument is invalid
sets _ERROR_=1
returns the substring that extends from the position that you specified to the end of the string.
If the substring that you specify extends past the end of the string, SUBPAD pads the result with blanks to yield the length that you requested . If the substring that you specify extends past the end of the string, SUBSTR
writes a note to the log stating that the third argument is invalid
sets _ERROR_=1
returns the substring that extends from the position that you specified to the end of the string.
