All comments are ignored at run-time.

The last comment type is a block comment where any number of comment lines can exist between /* and */.

Comments are useful to improve the readability of a program or help with debugging. Typically, the first few lines of a jCL program are used to describe the program, identify the programmer and record the date it was last modified.

# Note

Comments can be used within grouped commands (more than one command on a single line) but care must be taken though to ensure they will not conflict with normal command syntax.

# Example

001 PQN
002 C This program will...
003 C Created by A. Programmer, dd/mm/yy
004 C Last modified by:...
005 RI
006 RO
007 10 T C, (5, 10), "Password :",+
008 HECHO OFF
009 P
010 IP %1 \C Input password
