1.10 String operations
1.10
Overview
Further string manipulations are provided in addition to the conventional operations
"Assignment" and "Comparison" described in this section:
Parameters
Type conversion to STRING:
STRING_ERG = <<any type
STRING_ERG = AXSTRING (AXIS)
Type conversion from STRING:
BOOL_ERG = ISNUMBER (STRING)
REAL_ERG = NUMBER (STRING)
AXIS_ERG = AXNAME (STRING)
Concatenation of strings:
any type
Conversion to lower/upper case:
STRING_ERG = TOUPPER (STRING)
STRING_ERG = TOLOWER (STRING)
Length of the string:
INT_ERG = STRLEN (STRING)
Look for character/string in the
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 = STRINGARRAY [IDX_FELD,
IDX_CHAR]

Special meaning of the 0 char
The 0 char is interpreted internally as end-of-string. Replacing a character by the 0 character
truncates the string.
