Conditional constructions and long variables

Top  Previous  Next

An alternative of operator "If" may be used in the command line. A part of the command line must be enclosed into angle brackets in the following form:

<<SpecialVariable>:<string1>|<string2>>

This construction will be replaced with <string1> in the command line, if <SpecialVariable> – not an empty value, otherwise <string2> will be added.

In the construction <string2> may be missing, <string1> may be empty. <SpecialVariable> as other variables may be inserted in any position in the command line, if enclosed in '%'.

Another variant of conditional substitution (similar to switch in C):

<SpecialVariable=value1:string1|=value2:string2|…|=valueN:stringN|:stringOther>

If variable value is valueX, then the construction will be replaced with appropriate stringX. If no value matched, stringOther is inserted, and colon character ":" ahead of stringOther is optional, unless stringOther starts with ":" or "=".

 

(!) These constructions may be enclosed into each other.

 

<SpecialVariable> may have following values:
