Booting into 80 Columns..........................Bill Morgan

The ProDOS version of the S-C Macro Assembler is carefully written to operate in either 40 or 80 columns.  When you boot the disk the assembler starts out in the 40 column mode, because we couldn't take for granted that you would have (or want) the 80 column display.  Well it turns out that most people (myself included) are using 80 columns and are getting tired of typing PR#3 every time they start up the assembler.

Marc Wolfgram called up today from Wisconsin to ask how to make the assembler start up in 80 columns, and that finally got me around to finding out how.  It's embarassingly easy:  just a two-byte patch.  Here's the procedure, assuming you're in S-C Macro Assembler ProDOS:

!lm+10
UNLOCK SCASM.SYSTEM
BLOAD SCASM.SYSTEM,A$2000,TSYS
$6001:00 C3
BSAVE SCASM.SYSTEM,A$2000,TSYS,L17920
LOCK SCASM.SYSTEM
!lm-10

We just changed the IO.INIT call from JMP MON.HOME to JMP $C300, and that's all there is to it!  Now the next time you boot up, the assembler will be in 80 column mode.  RESET will return you to 40 columns.  PR#3 or NEW will restore 80 columns.

Thanks, Marc, for prompting me to find out about this.
