Text Operation Error Status (STR_ERR_STAT)

When an error occurs during execution of text operation, an error is set to the Text Operation Error Status [e: STR_ERR_STAT]. "0" in [e: STR_ERR_STAT] indicates a normal condition, and values other than "0" stored in [e: STR_ERR_STAT] indicate error states. The most recent error is stored in the Text Operation Error Status [e: STR_ERR_STAT]. The Text Operation Error Status can be set up with [SIO Port Operation/Label Settings] under the D-Script Toolbox menu. The following table lists the text operation errors.

A string of at least 256 bytes is directly included in the argument for the following functions: _strset ( ), _strlen ( ), _strcat ( ), _strmid ( ), and IO_READ_WAIT ( ).
Or, a string exceeding the data buffer size is created during execution of the _strcat ( ) or _ldcopy ( ) function.
For example,
_strcat(databuf0, databuf1)
If the above function is executed when a string of 1020 bytes is stored in databuf0, and a string of 60 bytes is stored in databuf1, as the databuf0 size of 1024 bytes is exceeded, it will result in an error.

Invalid character code is used as a parameter for _hexasc2bin( ) or _decasc2bin( ).
For example,
a character code other than "0" to "9", "A" to "F", or "a" to "f" (such as "G") is set as the second parameter for _hexasc2bin( ).

Retrieval of a character string longer than the character string specified with the "_strmid ( )" Function is attempted. Or, an offset value greater than the specified string is designated.
For example,
_strmid (databuf0, "12345678", 2, 8)
Retrieval of 8 characters from offset 2 is attempted

It is stored in the Error Status during execution of each function.

To check the error [e: STR_ERR_STAT], write the following statements. You can confirm the error with the following expression.

Example expression:

if ([e:STR_ERR_STAT] <> 0)     // check error status
{
 set ([b:[#INTERNAL]LS005000])// Turn ON the error display lamp
}
endif
