Example 7.32 Search a string
Script
[D0000] = STRSTR([D0100], [D0200]);
Operation Description
Searches for the search string "DEFG" that starts from D0200 in the string to be searched "ABCDEFGHIJKLMNO" that starts from
D0100 and stores the position of the occurrence of the string in D0000. If not found, -1 is stored in D0000.
If "?" is specified as a character to search for, it is handled as any 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.
Note: The maximum length of the search string is 128 characters.
