Anomalies

Chapter 9

9–5

STRING# NOT ALLOCATED — This error occurs if you attempt to

access a string that is outside the allocated string memory when using

CALLs 60, 61, 64, 65, 66, 67, or 68.

Example:

u10 STRING 100,9 REM 10 STRINGS ALLOCATED$

(0)–$(9)

u20 PUSH 5,12 REM REPEAT CHAR 5 TIMES

IN$(12)

u30 CALL 60

uRUN

ERROR — STRING # NOT ALLOCATED

Error occurs because STRING 12 is outside the area reserved for strings.

#BYTES/STRING EXCEED 254 — This error occurs if the STRING X,X

command allocates more characters per string than is allowed using CALL

62.

Example:

u10 STRING 1000,300

INSUFFICIENT NUMBER OF STRING CHARACTERS This error

occurs if you do not use the required minimum string lengths when using

CALL 62.

BAD # PUSHED — This error occurs if the string position pointer is zero

(invalid position) using CALL 66.

INSUFFICIENT STRING SIZE — This error occurs if the resulting string

cannot hold all required characters when using CALLs 61 or 66.

Example:

u10 STRING 100,9 REM MAX OF 9 CHR’S/STRING

u20 $(0)=“01234567”

u30 $(1)=“890”

If you attempt to insert or concatenate, an error occurs because the

resulting string requires 11 characters.
