 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

There isn't an ISO standard specifically for the BASIC language now. There was something like it (defining syntax) but it was withdrawn in 1991. A replacement standard which did include some info on BASIC was also withdrawn. The Dartmouth group tried to get a ANSI standard but eventually gave up, finally releasing True BASIC, which contains a lot of what they wanted in an ANSI standard. An early attempt at a standard in 1987 was roundly ignored by everyone as Microsoft had already had their version on millions of machines, which were then becoming obsolete. There's no point in calling something a standard if it's the only member of the group. :) MSX BASIC was probably more of a standard because several different manufacturers included it, Some included hardware extensions to it, but they were all upwardly compatible. That goes for MSX2 as well, it will still run MSX1 BASIC programs. It still doesn't negate my point though, that PRINT USING is a dog and has rarely, if ever, appeared in ROM versions because of that. :) Remember, MMBasic is ROM based, it's not a disk BASIC.

<pedant mode> It was supported in Locomotive basic which was ROM based on the 3rd most popular 8bit machines of the middle 80s. Milions of the buggers. Here's proof  </pedant mode> your point about it being a CPU hog is well made. h Edited 2024-08-05 07:06 by CaptainBoing |

yes I tried Courier New and it would work but it does not look good at larger sizes Edited 2024-08-05 14:17 by zeitfest |

No, it's not very pretty but is it possible to change fonts just for the numbers? An alternative would be to search the web for mono-spaced fonts. You might find one that you like. Bill Keep safe. Live long and prosper. |

I didn't know Locomotive BASIC had it. Trust Alan Michael Sugar Trading to be b*** awkward... ;) PRINT FORMAT$(2.99,"%0 10 g" to you too. :) or..... f$=" $$$$ ##### $$$ " a$="No" n=25.4 b$="ABC" Print using$(f$, a$,n,b$) Function using$(f$, a$,n,b$) Local o$,i,j,k o$=Space$(Len(f$)) i=Instr(1,f$,"$") j=Instr(i,f$," ")-1 k=j-Len(a$) MID$(o$,k)=a$ i=Instr(j+1,f$,"#") j=Instr(i,f$," ")-1 MID$(o$,i)=Str$(n) i=Instr(j+1,f$,"$") j=Instr(i,f$," ")-1 k=j-Len(b$) MID$(o$,k)=b$ 'Print ">"o$"<" using$ = o$ End Function .

Other monospaced fonts in Windows are Lucida Console and Consolas VK7JH MMedit MMBasic Help |

It's in TRS-80 Level II BASIC, Model III BASIC, Altair BASIC (ROM version), all in ROM. The TRS-80 was the most popular computer of 1978 and had more units being used than any other company. This means that PRINT USING wasn't rare at all in a ROM-based BASIC. |

I just pulled up the TRS-80 Level II manual at: http://www.akhara.com/trs-80/docs/model1/Level%20II%20BASIC%20Reference%20Manual%20(1979)(Radio%20Shack)(pdf).zip On pages starting at 3-4 the 'Print Using' command is documented. I was surprised they didn't include left and right justification of the numbers. But other than that it did provide a lot of help getting things formatted properly. It would appear the author of the 'Print Using' envisioned it would be used heavily for printing checks. There is a lot of emphasis on printing the $ sign immediately in front of the number and filling unused space with * characters. |
