CALL 61 – String Append Purpose
Use CALL 61 to append one string to the end of another string. This CALL
expects two string arguments. The first is the string number of the string to be
appended and the second is the string number of the base string. If the resulting
string is longer than the maximum string length, the append characters are lost.
There are no output arguments. This is a string concatenation assignment:
(example:
$(1)=$(1)+$(2) ).
Syntax
PUSH [string number to be appended]
PUSH [base string number]
CALL 61
IMPORTANT
If the new string length exceeds the length allocated by the string
command, an error message is printed on the console device and
the module enters Command mode.
