WSREPLACE replaces each character from \t, \f, \v, \n in a source buffer encoded as CHARACTER by a blank. This function returns a size_t 1 value that indicates the number of bytes that are written into the target buffer.
>>-WSREPLACE(p,m,q,n)------------------------------------------><
If the address of the target buffer is zero, the number of bytes to be written is returned. If the target buffer is not large enough, a value of -1 is returned. If the target buffer is large enough, the number of bytes that is written to the buffer is returned.
