# TR$ and LET A$=A$+B$ on the ZX80

String handling on the ZX80 is reasonably good. The 4K Integer Basic lets the user print, input, and compare strings. and do specialized routines that will transform numbers into strings or characters. Sinclair’s Integer Basic has no string concatenation commands at all. The first will truncate a string from the right side, the second will concatenate two strings.
