TFORMCVT: Converting From TGAL to TFORM
11387 Tandem Computers Incorporated E-11
BLANK Command
\BLANK " char "
TFORMCVT doesn’t output a TFORM command for this command, but
sets an internal flag to cause all instances of the specified character to be
output as the trigger character followed by “#”. If the trigger character is
“\”, TFORMCVT replaces the required blank character with “\#”.
\BLANK
TFORMCVT turns off the internal flag.
Tips
When the BLANK command is controlled by an IF command,
TFORMCVT still outputs all instances of the specified character as
“\#”, regardless of the state of the TGAL variable.
In TGAL, the required blank character has no meaning in strings that
are parameters for commands. TFORMCVT leaves the specified
required blank character in these strings.
