String operations

Overview
In addition to the classic operations "assignment" and
"comparison" described in this section, the following further
string manipulations are possible:
Explanation
Type conversion to STRING:
STRING_ERG = <<bel._Typ
STRING_ERG = AXSTRING (AXIS)
Type conversion from STRING:
BOOL_ERG = ISNUMBER (STRING)
REAL_ERG = NUMBER (STRING)
AXIS_ERG = AXNAME (STRING)
Chaining of strings:
1)
bel._Typ << bel. Typ
Conversion to lower/upper case:
STRING_ERG = TOUPPER (STRING)
STRING_ERG = TOLOWER (STRING)
Length of string:
INT_ERG = STRLEN (STRING)
Search for character/string in string:
INT_ERG = INDEX (STRING, CHAR)
INT_ERG = RINDEX (STRING, CHAR)
INT_ERG = MINDEX (STRING, STRING)
INT_ERG = MATCH (STRING, STRING)
Selection of a substring:
STRING_ERG = SUBSTR (STRING, INT)
STRING_ERG = SUBSTR (STRING, INT, INT)
Selection of a single character:
CHAR_ERG = STRINGVAR [IDX]
CHAR_ERG = STRINGFIELD [IDX_FIELD, IDX_CHAR]
1)
"bel._Typ" stands for variable types INT, REAL, CHAR, STRING and BOOL.
