Operation description
Searches for the search string “DEFG” that starts from LDR200 in the string to be searched “ABCDEFGHIJKLMNO” that
starts from LDR100 and stores the position of the occurrence of the string in LDR0. If not found, -1 is stored in LDR0.
If “?” is specified as a character to search for, it is handled as an arbitrary single-byte character.
When specifying “?” (0x3F) as a character, specify it as “~?” (0x7E3F) in two bytes.
When specifying “~” (0x7E) as a character, specify it as “~~” (0x7E7E) in two bytes.
When searching for “DEFG” and the string was found
When searching for “WXYZ” and the string was not found
■ Example 5.7.29 Search a string
[LDR 0] = STRSTR([LDR 100], [LDR 200]);
• The maximum number for the search string is 128 characters.
• Only internal devices can be used.
