Function
The "conversion to lower/upper case letters" function allows all of the letters of a string to be
converted into a standard representation.
Syntax
<STRING_ERG>=TOUPPER("<string>")
<STRING_ERG>=TOLOWER("<string>")
Significance
TOUPPER: Using the TOUPPER command, all of the letters in a character string
are converted into upper case letters.

are converted into lower case letters.
Character string that is to be converted
<string>:
Type: STRING
Variable for the result of the conversion

Example

capitalization (upper or lower case):

...
IF "LEARN.CNC"==TOUPPER(STRG) GOTOF LOAD_LEARN
