&HEX-AS-SIGNED

Restriction: This topic applies only when the AppMaster Builder AddPack has been installed, and applies only to Windows platforms.

Syntax:

&HEX-AS-SIGNED (&variablename[, &targetlength])

Aliases:

&hex-as-signed (&variablename[, &targetlength])
&Hex-As-Signed (&variablename[, &targetlength])
&HEXASSIGNED (&variablename[, &targetlength])
&hexassigned (&variablename[, &targetlength])
&HexAsSigned (&variablename[, &targetlength])

Comments:

When converting hex to an equivalent binary string, &targetlength determines which bit is interpreted as a sign bit. For example,

&HEX-AS-SIGNED ("7F", 1) = 127
&HEX-AS-SIGNED ("80", 1) = -128

For hex 80 (binary 10000000), the eighth bit from the right (counting the rightmost bit as 1) is the sign bit, but

&HEX-AS-SIGNED ("7F", 2) = 127
&HEX-AS-SIGNED ("80", 2) = 256

For hex 80 (binary 0000000010000000), the 16th bit from the right is the sign bit.

Example:

&HEX-AS-SIGNED ("00")  = 0
&HEX-AS-SIGNED ("01")  = 1
&HEX-AS-SIGNED ("0A")  = 10
&HEX-AS-SIGNED ("0F")  = 15
&HEX-AS-SIGNED ("10")  = 16
&HEX-AS-SIGNED ("13")  = 19
&HEX-AS-SIGNED ("6F")  = 111
&HEX-AS-SIGNED ("7F")  = 127
&HEX-AS-SIGNED ("80")  = 128
&HEX-AS-SIGNED ("FF")  = 255
&HEX-AS-SIGNED ("F")   = 15
&HEX-AS-SIGNED ("00", 1) = 0
&HEX-AS-SIGNED ("01", 1) = 1
