LOWER Function

Lowers system delimiters within a string to the next lower level.

Syntax

LOWER(string)

Syntax Elements

string An expression that evaluates to the string to be processed.

Operation

The LOWER function converts system delimiters in a string to the next lower level as shown in the following table:

Delimiter	ASCII Equivalent	Lowered To	ASCII Equivalent
Segment/item mark.	255	Attribute mark	254
Attribute mark	254	Value mark	253
Value mark	253	Subvalue mark	252
Subvalue mark	252	Start of buffer/text mark	251
Start of buffer/text mark	251	Remains unchanged	251

Example

STR = "A":@IM:"B":@AM:"CýDüE":@TM:"F"
FOR I = 1 TO LEN(STR)
   PRINT SEQ(STR[I,1]):" ":
NEXT I
PRINT
SL = LOWER(STR)
FOR I = 1 TO LEN(SL)
   PRINT SEQ(SL[I,1]):" ":
NEXT I
PRINT

This example defines a string containing each of the system delimiters and prints the decimal equivalent of each character. It then applies the LOWER function to the string and prints the result in the same way. The output is as follows:

65 255 66 254 67 253 68 252 69 251 70
65 254 66 253 67 252 68 251 69 251 70
