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:
