Inno Setup Preprocessor: Command Line Compiler Execution

If Inno Setup Preprocessor is installed the console-mode compiler ISCC.exe automatically provides extra parameters to control Inno Setup Preprocessor:

/D<name>[=<value>] Emulate #define public <name> <value>
/$<letter>(+|-) Emulate #pragma option -<letter>(+|-)
/P<letter>(+|-) Emulate #pragma parseroption -<letter>(+|-)
/I<paths> Emulate #pragma include <paths>
/J<filename> Emulate #include <filename>
/{#<string> Emulate #pragma inlinestart <string>
/}<string> Emulate #pragma inlineend <string>
/V<number> Emulate #pragma verboselevel <number>

Example: iscc /$c- /Pu+ "/DLicenseFile=Trial License.txt" /Ic:\inc;d:\inc /Jdefines.iss "c:\isetup\samples\my script.iss"
