Conversion functions

The functions presented in this section are used for explicit conversion.

String conversion for literals, C literals, X literals

FROM-C-LITERAL( )	Converts a C literal to the string it represents (reverse function of TO-C-LITERAL)
FROM-X-LITERAL( )	Converts an X literal to the string it represents (reverse function of TO-X-LITERAL)
TO-C-LITERAL( )	Converts a string to a C literal
TO-X-LITERAL( )	Converts a string to an external hexadecimal representation of the string
BOOLEAN( )	Converts an expression to BOOLEAN
INTEGER( )	Converts an expression to INTEGER
INTEGER-TO-X-LITERAL( )	Converts an integer to a 4-byte long X literal which contains the coding of the integer (inverse function to X-LITERAL-TO-INTEGER)
STRING( )	Converts an expression to STRING
VARIABLE-TO-STRING( )	Converts an S variable to an SDF string
HASH-STRING( )	Codes an expression as a string
HASH-VALUE( )	Codes an expression as an integer value
X-LITERAL-TO-INTEGER( )	Converts a string which is up to 4 bytes long to an integer (inverse function to INTEGER-TO-X-LITERAL)

Character by character (re)coding

CHARACTER-TO-INTEGER( )	Supplies the value in EBCDI code as an integer for the specified character
INTEGER-TO-CHARACTER( )	Supplies the character coded with this value in EBCDI code for a specified integer from 1 to 255
TRANSLATE( )	Replaces a string with another string defined by the user
TRANSLATE-BOOLEAN( )	Allocates another expression defined by the user to the result of a Boolean expression
