SYMPTOM(s):
Can't PUT past the end of the MEMPTR. (4791)
Application uses LENGTH(string-var, "CHARACTER") to determine length of a string.
String string-var contains non-printable (invisible) multi-byte characters.
Result of LENGTH(string-var, "CHARACTER") is used to set the size of a MEMPTR variable to hold a string:
SET-SIZE(memptr-var) = LENGTH(string-var, "CHARACTER") + 1.
Assigning the string string-var to the MEMPTR variable results in system error 4791:
PUT-STRING(memptr-var,1) = string-var.
CAUSE:
LENGTH(string-var, "CHARACTER") will return length in characters, including double-byte characters.
FIX:
Use LENGTH(string-var, "RAW") to express the length of the variable in bytes or ensure that string-var does not contain double-byte characters.
