Using Irvine32.inc

Each string-handling procedure assumes the use of null-terminated strings. Even when not explicitly requested, write a short driver program for each exercise solution that tests your new procedure.

Write a procedure named Str_remove that removes n characters from a string. Pass a pointer to the position in the string where the characters are to be removed. Pass an integer specifying the number of characters to remove. The following code, for example, shows how to remove xxxx from target:

.data

target BYTE "abcxxxxdefghijklmop",0

.code

INVOKE Str_remove, ADDR [target+3], 4
