MidA ( string, start {, length } )
Argument |
Description |
|---|---|
string |
The string from which you want characters returned. |
start |
A long specifying the position of the first byte you want returned (the position of the first byte of the string is 1). |
length (optional) |
A long whose value is the number of bytes you want returned. If you do not enter length or if length is greater than the number of bytes to the right of start, MidA returns the remaining bytes in the string. |
String. Returns characters specified by the number of bytes in length of string starting at the byte specified by start. If start is greater than the number of bytes in string, the MidA function returns the empty string (“”). If length is greater than the number of bytes remaining after the start byte, MidA returns the remaining bytes. The return string is not filled with spaces to make it the specified length.
MidA replaces the functionality that Mid had in DBCS environments in PowerBuilder 9. In SBCS environments, Mid and MidA return the same results.
