I'm teaching myself assembler programming while exploring TSS/8 following the EDUsystem-50 Users Guide on BitSavers.org.
Working my way up to "Hello, World!", I've learned from an example in the Users Guide how to plug successive character codes into the accumulator and print them out with TLS/TSF.
For my next step, I've found the TEXT pseudo-op that packs a string into memory two characters per word, and the SAS instruction that outputs a string of characters from memory stored one per word.
Does PAL-D have facilities for doing any of the following:
- Convert TEXT-packed 2-char-per-word data into 1-char-per-word format for printing with SAS
- Unpack TEXT data for 1-char-at-a-time printing with TLS/TSF
- Load character string data into memory in the format expected by SAS
Thanks.
