DELETE Removes a file from disk; or lines from a program; or an object from memory Implemented by: ansifull, , altair12K, , , cbmv7, cbmv3.5, level2, , bw32, With variations: , (ISAM instruction), , , (program edition), (destroy an object) Also written as: Usage ECMA's FullBASIC standard defines DELETE as a file-related operation, even though in many commercial and popular BASICs the keyword was already in use as an edition command.

cbm Commodore BASIC cbm Keywords The BASIC used in the famous 8-bit Commodore machines such as PET, VIC-20, C64, 16, Plus/4 and C128. Originally, it was pretty much the Microsoft port of its BASIC-80 for the 6502 processor, later improved by Commodore developers into a number of versions with some meaningful differences. None of them however was nearly as popular as the rather crude one known as

DEL Removes lines from a program stored in memory Implemented by: , ataplus, , colorext With variations: atxl (statement) Also written as: Usage Easily understood as a contraction, DEL has been often implemented for a different purpose than that of DELETE. In Tandy CoCo II BASIC, at least, DEL is an edition command for erasing program lines.

ASNG

Fabricio Rocha (supernariz@undisclosed.example.com) — 2024-03-08T18:54:49+00:00

ASNG Returns the arcsine of its argument, in gradians Implemented by: bw32 With variations: Also written as: Usage The return value of this function is in grads or gradians, according to the documentation source adopted, within the range -100 to 100, where -100 gradians is the same of -90 degrees and 100 gradians equals to 90 degrees.

ASND

Fabricio Rocha (supernariz@undisclosed.example.com) — 2024-03-08T18:48:27+00:00

ASND Returns, in degrees, the arcsine of its argument. Implemented by: bw32 With variations: Also written as: Usage R = ASND(X) The fundamental difference between this function and ASN is that its return values are in degrees, between -90 and 90. The value of X must be a number within the range -1 to 1.

ASIN

Fabricio Rocha (supernariz@undisclosed.example.com) — 2024-03-08T18:44:24+00:00

ASIN Returns the arc-sine of the given numeric value. See ASN. Implemented by: ansifull, bw32, , , With variations: Also written as: ASN, ARCSIN functions trigonometry mathematics

ARCSIN

Fabricio Rocha (supernariz@undisclosed.example.com) — 2024-03-08T18:43:13+00:00

ARCSIN Returns the arc-sine of a given number. See ASN. Implemented by: bw32 With variations: Also written as: ASN, ASIN functions trigonometry

ASN

Fabricio Rocha (supernariz@undisclosed.example.com) — 2024-03-08T18:41:00+00:00

ASN Returns the arcsine of its argument, in radians. Implemented by: zx81, spectrum, , bw32 With variations: Also written as: ASIN, ARCSIN Usage Variations Examples Comments ASN is also found, with this name, in historical implementations of BASIC for IBM System/360 and System/370, according to the documentation of

COSH

Fabricio Rocha (supernariz@undisclosed.example.com) — 2024-03-08T18:24:45+00:00

COSH Returns the hyperbolic cosine of its argument Implemented by: bw32, With variations: Also written as: Usage Variations Examples Comments The BASIC Cookbook points out that BASICs which don't implement the function can achieve the same results, for a given X argument, with the following formula:

COT

Fabricio Rocha (supernariz@undisclosed.example.com) — 2024-03-08T18:21:57+00:00

COT Returns the co-tangent of its argument Implemented by: dartmouth4, ansifull, bw32 With variations: Also written as: Usage Variations Examples Comments The BASIC Cookbook points out that BASICs which don't implement the function can achieve the same results, for a given X argument, with the following formula:

SEC

Fabricio Rocha (supernariz@undisclosed.example.com) — 2024-03-08T18:20:21+00:00

SEC Returns the secant of its argument Implemented by: ansifull, bw32 With variations: Also written as: Usage Variations Examples Comments The formula 1/COS(X) is the easy substitute of SEC in BASICs that don't implement it, as brought by 1978's The BASIC Cookbook

SINH

Fabricio Rocha (supernariz@undisclosed.example.com) — 2024-03-08T18:16:33+00:00

SINH Returns the hyperbolic sine of a given value Implemented by: bw32, With variations: Also written as: Usage Variations Examples Comments The BASIC Cookbook points out that BASICs which don't implement the function can achieve the same results, for a given X argument, with the following formula:

TANH

Fabricio Rocha (supernariz@undisclosed.example.com) — 2024-03-08T18:13:56+00:00

TANH Returns the hyperbolic tangent of its argument Implemented by: bw32, With variations: Also written as: Usage Variations Examples Comments The BASIC Cookbook points out that BASICs which don't implement the function can achieve the same results, for a given X argument, with the following formula:

ACOS

Fabricio Rocha (supernariz@undisclosed.example.com) — 2024-03-08T15:17:08+00:00

ACOS Returns the arc-cosine of a number given as an argument from -1 to 1 Implemented by: ansifull, bw32, , , With variations: Also written as: Usage PRINT ACOS(0.9) Comments The arc-cosine is the inverse function of the cosine trigonometric function. It is the length of the arc whose cosine is its argument, and, as a proportion from 0 to 1 of the circle radius, this is the same as the angle, in radians, whose cosine is the argument.
