HELP SYSTEM SET FLAGS
This command presents the user with a chart listing the characters of
SYS_SETFLAGS, a string containing 14 characters that represent flags
set by the SET command. You can use the variable SYS_SETFLAGS to
determine if a particular SET command option is ON or OFF.
HELP SYSTEM VARIABLES
This command presents short definitions of system variables that
TFORM creates and maintains. You can use these variables in
expressions. System variables are described in Section 5.
Tips
The charts provided by the HELP SYSTEM DEFINE CHARACTERS,
HELP SYSTEM PRINT, and HELP SYSTEM SET commands supply you
with the character strings that make up the SYS_CHARS,
SYS_PRINTFLAGS, and SYS_SETFLAGS variables. You can evaluate
these strings to determine the current values of the control characters
that can be changed by the DEFINE command and which command
options are ON in the PRINT and SET commands, respectively.
You can see that a command option is ON if the flag corresponding to
that option is a “1”; conversely, a “0” means the option is OFF. For
example, suppose you evaluate the eighth character of the
SYS_SETFLAGS string. As the chart shows, this string character
corresponds to the SET JOIN option of the SET command. If
SYS_SETFLAGS returns a “0,” the SET JOIN option is OFF.
