The question isn't limited to *8-bit* micros, and HP is only one of the examples.

The question and answer seem to imply that the alternate BASIC string handling syntax on 8-bit computers came from HP

@another-dave I don’t know much about minis, but LEFT$ seems to have appeared on micros early on; 8K Altair BASIC had it in 1975.

| May 8, 2019 at 12:06 | comment | added | dave | I do however think I used the LEFT$/RIGHT$ syntax around 1971, dialed in to the UK Open University computer system (I had a maths teacher doing an OU degree in computer science), which I think was running on some HP mini. | |
| May 8, 2019 at 12:01 | comment | added | dave | For reference, both approaches seem to be revisionist treatments :-). BASIC comes from Dartmouth. 4th edition BASIC had the CHANGE statement to convert between a string variable and an array of ASCII character-codes.. | |

| May 8, 2019 at 11:46 | comment | added | supercat | HT2000 Basic worked as described; any microcomputer BASICs probably derived such behavior from the HP. | |
| May 8, 2019 at 11:32 | comment | added | Omar and Lorraine | Why and how are you distinguishing micros from minis? A given BASIC could be made to run on either. | |
