VRD. Command

Variable Remove Doubles

 

 

Intention

 

This Command can be used to make strings have only single delimiters.

 

The Command has two modes: Text-mode and Binary mode.

In Text mode ASCII 32 and ASC 9 (TAB's and SPACES) are processed to single Spaces in one Run. In text-mode, the string is not allowed to contain ASCII(0).

 

In Binary Modes all characters are allowed.

 

 

 

Syntax

 

VRD.[P1][|P2]

 

 

Parameter Explanation

 

P1 - is Source and Target-variable

 

P2 - is obsolete for Text-Trimming.

 In that case it just trims away all spaces left and right.

 If Parameter 2 is "all" the all  characters from CHR$(0 to 32)

 will be trimmed.

 

 

 

 

Example
